62 * struct bus_type - The bus type of the device
63 *

68 * @bus_groups: Default attributes of the bus.
69 * @dev_groups: Default attributes of the devices on the bus.
70 * @drv_groups: Default attributes of the device drivers on the bus.
71 * @match: Called, perhaps multiple times, whenever a new device or driver
72 * is added for this bus. It should return a nonzero value if the
73 * given device can be handled by the given driver.
74 * @uevent: Called when a device is added, removed, or a few other things
75 * that generate uevents to add the environment variables.
76 * @probe: Called when a new device or driver add to this bus, and callback
77 * the specific driver's probe to initial the matched device.
78 * @remove: Called when a device removed from this bus.
79 * @shutdown: Called at shut-down time to quiesce the device.
80 *
81 * @online: Called to put the device back online (after offlining it).
82 * @offline: Called to put the device offline for hot-removal. May fail.
83 *
84 * @suspend: Called when a device on this bus wants to go to sleep mode.
85 * @resume: Called to bring a device on this bus out of sleep mode.
86 * @pm: Power management operations of this bus, callback the specific
87 * device driver's pm-ops.
88 * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
89 * driver implementations to a bus and allow the driver to do
90 * bus-specific setup
91 * @p: The private data of the driver core, only the driver core can
92 * touch this.
93 * @lock_key: Lock class key for use by the lock validator

95 * A bus is a channel between the processor and one or more devices. For the
96 * purposes of the device model, all devices are connected via a bus, even if
97 * it is an internal, virtual, "platform" bus. Buses can plug into each other.
98 * A USB controller is usually a PCI device, for example. The device model
99 * represents the actual connections between buses and the devices they control.
100 * A bus is represented by the bus_type structure. It contains the name, the
101 * default attributes, the bus' methods, PM operations, and the driver core's
102 * private data.

658 /**
659 * struct device - The basic device structure
660 * @parent: The device's "parent" device, the device to which it is attached.
661 * In most cases, a parent device is some sort of bus or host
662 * controller. If parent is NULL, the device, is a top-level device,
663 * which is not usually what you want.
664 * @p: Holds the private data of the driver core portions of the device.
665 * See the comment of the struct device_private for detail.
666 * @kobj: A top-level, abstract class from which other classes are derived.
667 * @init_name: Initial name of the device.
668 * @type: The type of device.
669 * This identifies the device type and carries type-specific
670 * information.
671 * @mutex: Mutex to synchronize calls to its driver.
672 * @bus: Type of bus device is on.
673 * @driver: Which driver has allocated this
674 * @platform_data: Platform data specific to the device.
675 * Example: For devices on custom boards, as typical of embedded
676 * and SOC based hardware, Linux often uses platform_data to point
677 * to board-specific structures describing devices and how they
678 * are wired. That can include what ports are available, chip
679 * variants, which GPIO pins act in what additional roles, and so
680 * on. This shrinks the "Board Support Packages" (BSPs) and
681 * minimizes board-specific #ifdefs in drivers.
682 * @driver_data: Private pointer for driver specific info.
683 * @power: For device power management.
684 * See Documentation/power/devices.txt for details.
685 * @pm_domain: Provide callbacks that are executed during system suspend,
686 * hibernation, system resume and during runtime PM transitions
687 * along with subsystem-level and driver-level callbacks.
688 * @pins: For device pin management.
689 * See Documentation/pinctrl.txt for details.
690 * @numa_node: NUMA node this device is close to.
691 * @dma_mask: Dma mask (if dma'ble device).
692 * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all
693 * hardware supports 64-bit addresses for consistent allocations
694 * such descriptors.
695 * @dma_pfn_offset: offset of DMA memory range relatively of RAM
696 * @dma_parms: A low level driver may set these to teach IOMMU code about
697 * segment limitations.
698 * @dma_pools: Dma pools (if dma'ble device).
699 * @dma_mem: Internal for coherent mem override.
700 * @cma_area: Contiguous memory area for dma allocations
701 * @archdata: For arch-specific additions.
702 * @of_node: Associated device tree node.
703 * @acpi_node: Associated ACPI device node.
704 * @devt: For creating the sysfs "dev".
705 * @id: device instance
706 * @devres_lock: Spinlock to protect the resource of the device.
707 * @devres_head: The resources list of the device.
708 * @knode_class: The node used to add the device to the class list.
709 * @class: The class of the device.
710 * @groups: Optional attribute groups.
711 * @release: Callback to free the device after all references have
712 * gone away. This should be set by the allocator of the
713 * device (i.e. the bus driver that discovered the device).
714 * @iommu_group: IOMMU group the device belongs to.
715 *
716 * @offline_disabled: If set, the device is permanently online.
717 * @offline: Set after successful invocation of bus type's .offline().
718 *
719 * At the lowest level, every device in a Linux system is represented by an
720 * instance of struct device. The device structure contains the information
721 * that the device model core needs to model the system. Most subsystems,
722 * however, track additional information about the devices they host. As a
723 * result, it is rare for devices to be represented by bare device structures;
724 * instead, that structure, like kobject structures, is usually embedded within
725 * a higher-level representation of the device.

121 * @needs_altsetting0: flag set when a set-interface request for altsetting 0
122 * has been deferred.
123 * @needs_binding: flag set when the driver should be re-probed or unbound
124 * following a reset or suspend operation it doesn't support.
125 * @dev: driver model's view of this device
126 * @usb_dev: if an interface is bound to the USB major, this will point
127 * to the sysfs representation for that device.
128 * @pm_usage_cnt: PM usage counter for this interface
129 * @reset_ws: Used for scheduling resets from atomic context.
130 * @reset_running: set to 1 if the interface is currently running a
131 * queued reset so that usb_cancel_queued_reset() doesn't try to
132 * remove from the workqueue when running inside the worker
133 * thread. See __usb_queue_reset_device().
134 * @resetting_device: USB core reset the device, so use alt setting 0 as
135 * current; needs bandwidth alloc after reset.
136 *
137 * USB device drivers attach to interfaces on a physical device. Each
138 * interface encapsulates a single high level function, such as feeding
139 * an audio stream to a speaker or reporting a change in a volume control.
140 * Many USB devices only have one interface. The protocol used to talk to
141 * an interface's endpoints can be defined in a usb "class" specification,
142 * or by a product's vendor. The (default) control endpoint is part of
143 * every interface, but is never listed among the interface's descriptors.
144 *
145 * The driver that is bound to the interface can use standard driver model
146 * calls such as dev_get_drvdata() on the dev member of this structure.
147 *
148 * Each interface may have alternate settings. The initial configuration
149 * of a device sets altsetting 0, but the device driver can change
150 * that setting using usb_set_interface(). Alternate settings are often
151 * used to control the use of periodic endpoints, such as by having
152 * different endpoints use different amounts of reserved USB bandwidth.
153 * All standards-conformant USB devices that use isochronous endpoints
154 * will use them in non-default settings.
155 *
156 * The USB specification says that alternate setting numbers must run from
157 * 0 to one less than the total number of alternate settings. But some
158 * devices manage to mess this up, and the structures aren't necessarily
159 * stored in numerical order anyhow. Use usb_altnum_to_altsetting() to

1010 * driver module is being unloaded.
1011 * @unlocked_ioctl: Used for drivers that want to talk to userspace through

1018 * try to continue using the device if suspend fails in this case.
1019 * Instead, let the resume or reset-resume routine recover from
1020 * the failure.
1021 * @resume: Called when the device is being resumed by the system.
1022 * @reset_resume: Called when the suspended device has been reset instead
1023 * of being resumed.
1024 * @pre_reset: Called by usb_reset_device() when the device is about to be
1025 * reset. This routine must not return until the driver has no active
1026 * URBs for the device, and no more URBs may be submitted until the

1030 * @id_table: USB drivers use ID table to support hotplugging.
1031 * Export this with MODULE_DEVICE_TABLE(usb,...). This must be set

1040 * @soft_unbind: if set to 1, the USB core will not kill URBs and disable
1041 * endpoints before calling the driver's disconnect method.
1042 * @disable_hub_initiated_lpm: if set to 0, the USB core will not allow hubs
1043 * to initiate lower power link state transitions when an idle timeout
1044 * occurs. Device-initiated USB 3.0 link PM will still be allowed.

1251 * usb_{snd,rcv}TYPEpipe(dev,endpoint), where the TYPE is "ctrl"
1252 * (control), "bulk", "int" (interrupt), or "iso" (isochronous).
1253 * For example usb_sndbulkpipe() or usb_rcvintpipe(). Endpoint
1254 * numbers range from zero to fifteen. Note that "in" endpoint two
1255 * is a different endpoint (and pipe) from "out" endpoint two.
1256 * The current configuration controls the existence, type, and

1258 * @stream_id: the endpoint's stream ID for bulk streams
1259 * @dev: Identifies the USB device to perform the request.
1260 * @status: This is read in non-iso completion functions to get the
1261 * status of the particular request. ISO requests only use it
1262 * to tell whether the URB was unlinked; detailed status for
1263 * each frame is in the fields of the iso_frame-desc.
1264 * @transfer_flags: A variety of flags may be used to affect how URB
1265 * submission, unlinking, or operation are handled. Different
1266 * kinds of URB can use different flags.
1267 * @transfer_buffer: This identifies the buffer to (or from) which the I/O
1268 * request will be performed unless URB_NO_TRANSFER_DMA_MAP is set
1269 * (however, do not leave garbage in transfer_buffer even then).
1270 * This buffer must be suitable for DMA; allocate it with
1271 * kmalloc() or equivalent. For transfers to "in" endpoints, contents
1272 * of this buffer will be modified. This buffer is used for the data
1273 * stage of control transfers.
1274 * @transfer_dma: When transfer_flags includes URB_NO_TRANSFER_DMA_MAP,
1275 * the device driver is saying that it provided this DMA address,
1276 * which the host controller driver should use in preference to the
1277 * transfer_buffer.
1278 * @sg: scatter gather buffer list, the buffer size of each element in
1279 * the list (except the last) must be divisible by the endpoint's
1280 * max packet size if no_sg_constraint isn't set in 'struct usb_bus'
1281 * @num_mapped_sgs: (internal) number of mapped sg entries
1282 * @num_sgs: number of entries in the sg list
1283 * @transfer_buffer_length: How big is transfer_buffer. The transfer may
1284 * be broken up into chunks according to the current maximum packet
1285 * size for the endpoint, which is a function of the configuration
1286 * and is encoded in the pipe. When the length is zero, neither
1287 * transfer_buffer nor transfer_dma is used.
1288 * @actual_length: This is read in non-iso completion functions, and
1289 * it tells how many bytes (out of transfer_buffer_length) were
1290 * transferred. It will normally be the same as requested, unless
1291 * either an error was reported or a short read was performed.
1292 * The URB_SHORT_NOT_OK transfer flag may be used to make such
1293 * short reads be reported as errors.
1294 * @setup_packet: Only used for control transfers, this points to eight bytes
1295 * of setup data. Control transfers always start by sending this data
1296 * to the device. Then transfer_buffer is read or written, if needed.
1297 * @setup_dma: DMA pointer for the setup packet. The caller must not use
1298 * this field; setup_packet must point to a valid buffer.
1299 * @start_frame: Returns the initial frame for isochronous transfers.
1300 * @number_of_packets: Lists the number of ISO transfer buffers.
1301 * @interval: Specifies the polling interval for interrupt or isochronous
1302 * transfers. The units are frames (milliseconds) for full and low
1303 * speed devices, and microframes (1/8 millisecond) for highspeed
1304 * and SuperSpeed devices.
1305 * @error_count: Returns the number of ISO transfers that reported errors.
1306 * @context: For use in completion functions. This normally points to
1307 * request-specific driver context.
1308 * @complete: Completion handler. This URB is passed as the parameter to the
1309 * completion function. The completion function may then do what
1310 * it likes with the URB, including resubmitting or freeing it.
1311 * @iso_frame_desc: Used to provide arrays of ISO transfer buffers and to
1312 * collect the transfer status for each buffer.
1313 *
1314 * This structure identifies USB transfer requests. URBs must be allocated by
1315 * calling usb_alloc_urb() and freed with a call to usb_free_urb().
1316 * Initialization may be done using various usb_fill_*_urb() functions. URBs
1317 * are submitted using usb_submit_urb(), and pending requests may be canceled
1318 * using usb_unlink_urb() or usb_kill_urb().
1319 *
1320 * Data Transfer Buffers:
1321 *
1322 * Normally drivers provide I/O buffers allocated with kmalloc() or otherwise
1323 * taken from the general page pool. That is provided by transfer_buffer
1324 * (control requests also use setup_packet), and host controller drivers
1325 * perform a dma mapping (and unmapping) for each buffer transferred. Those
1326 * mapping operations can be expensive on some platforms (perhaps using a dma
1327 * bounce buffer or talking to an IOMMU),
1328 * although they're cheap on commodity x86 and ppc hardware.
1329 *
1330 * Alternatively, drivers may pass the URB_NO_TRANSFER_DMA_MAP transfer flag,
1331 * which tells the host controller driver that no such mapping is needed for
1332 * the transfer_buffer since
1333 * the device driver is DMA-aware. For example, a device driver might
1334 * allocate a DMA buffer with usb_alloc_coherent() or call usb_buffer_map().
1335 * When this transfer flag is provided, host controller drivers will
1336 * attempt to use the dma address found in the transfer_dma
1337 * field rather than determining a dma address themselves.
1338 *
1339 * Note that transfer_buffer must still be set if the controller
1340 * does not support DMA (as indicated by bus.uses_dma) and when talking
1341 * to root hub. If you have to trasfer between highmem zone and the device
1342 * on such controller, create a bounce buffer or bail out with an error.
1343 * If transfer_buffer cannot be set (is in highmem) and the controller is DMA
1344 * capable, assign NULL to it, so that usbmon knows not to use the value.
1345 * The setup_packet must always be set, so it cannot be located in highmem.
1346 *
1347 * Initialization:
1348 *
1349 * All URBs submitted must initialize the dev, pipe, transfer_flags (may be
1350 * zero), and complete fields. All URBs must also initialize
1351 * transfer_buffer and transfer_buffer_length. They may provide the
1352 * URB_SHORT_NOT_OK transfer flag, indicating that short reads are
1353 * to be treated as errors; that flag is invalid for write requests.
1354 *
1355 * Bulk URBs may
1356 * use the URB_ZERO_PACKET transfer flag, indicating that bulk OUT transfers
1357 * should always terminate with a short packet, even if it means adding an
1358 * extra zero length packet.
1359 *
1360 * Control URBs must provide a valid pointer in the setup_packet field.
1361 * Unlike the transfer_buffer, the setup_packet may not be mapped for DMA
1362 * beforehand.
1363 *
1364 * Interrupt URBs must provide an interval, saying how often (in milliseconds
1365 * or, for highspeed devices, 125 microsecond units)
1366 * to poll for transfers. After the URB has been submitted, the interval
1367 * field reflects how the transfer was actually scheduled.
1368 * The polling interval may be more frequent than requested.
1369 * For example, some controllers have a maximum interval of 32 milliseconds,
1370 * while others support intervals of up to 1024 milliseconds.
1371 * Isochronous URBs also have transfer intervals. (Note that for isochronous
1372 * endpoints, as well as high speed interrupt endpoints, the encoding of
1373 * the transfer interval in the endpoint descriptor is logarithmic.
1374 * Device drivers must convert that value to linear units themselves.)
1375 *
1376 * If an isochronous endpoint queue isn't already running, the host
1377 * controller will schedule a new URB to start as soon as bandwidth
1378 * utilization allows. If the queue is running then a new URB will be
1379 * scheduled to start in the first transfer slot following the end of the
1380 * preceding URB, if that slot has not already expired. If the slot has
1381 * expired (which can happen when IRQ delivery is delayed for a long time),
1382 * the scheduling behavior depends on the URB_ISO_ASAP flag. If the flag
1383 * is clear then the URB will be scheduled to start in the expired slot,
1384 * implying that some of its packets will not be transferred; if the flag
1385 * is set then the URB will be scheduled in the first unexpired slot,
1386 * breaking the queue's synchronization. Upon URB completion, the
1387 * start_frame field will be set to the (micro)frame number in which the
1388 * transfer was scheduled. Ranges for frame counter values are HC-specific
1389 * and can go from as low as 256 to as high as 65536 frames.
1390 *
1391 * Isochronous URBs have a different data transfer model, in part because
1392 * the quality of service is only "best effort". Callers provide specially
1393 * allocated URBs, with number_of_packets worth of iso_frame_desc structures
1394 * at the end. Each such packet is an individual ISO transfer. Isochronous
1395 * URBs are normally queued, submitted by drivers to arrange that
1396 * transfers are at least double buffered, and then explicitly resubmitted
1397 * in completion handlers, so
1398 * that data (such as audio or video) streams at as constant a rate as the
1399 * host controller scheduler can support.
1400 *
1401 * Completion Callbacks:
1402 *
1403 * The completion callback is made in_interrupt(), and one of the first
1404 * things that a completion handler should do is check the status field.
1405 * The status field is provided for all URBs. It is used to report
1406 * unlinked URBs, and status for all non-ISO transfers. It should not
1407 * be examined before the URB is returned to the completion handler.
1408 *
1409 * The context field is normally used to link URBs back to the relevant
1410 * driver or request state.
1411 *
1412 * When the completion callback is invoked for non-isochronous URBs, the
1413 * actual_length field tells how many bytes were transferred. This field
1414 * is updated even when the URB terminated with an error or was unlinked.
1415 *
1416 * ISO transfer status is reported in the status and actual_length fields
1417 * of the iso_frame_desc array, and the number of errors is reported in
1418 * error_count. Completion callbacks for ISO transfers will normally
1419 * (re)submit URBs to ensure a constant transfer rate.
1420 *
1421 * Note that even fields marked "public" should not be touched by the driver
1422 * when the urb is owned by the hcd, that is, since the call to
1423 * usb_submit_urb() till the entry into the completion routine.

Here is an explanation of a rule violation arisen while checking your driver against a corresponding kernel.
Note that it may be false positive, i.e. there isn't a real error indeed. Please analyze a given error trace and related source code to understand whether there is an error in your driver.
Error trace column contains a path on which the given rule is violated. You can expand/collapse some entity classes by clicking on corresponding checkboxes in a main menu or in an advanced Others menu. Also you can expand/collapse each particular entity by clicking on +/-. In hovering on some entities you can see some tips. Also the error trace is bound with related source code. Line numbers may be shown as links on the left. You can click on them to open corresponding lines in source code.
Source code column contains a content of files related with the error trace. There is source code of your driver (note that there are some LDV modifications at the end), kernel headers and rule model. Tabs show a currently opened file and other available files. In hovering on them you can see full file names. On clicking a corresponding file content will be shown.
