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.

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.

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. 1424 */ 1425 struct urb { 1426 /* private: usb core and host controller only fields in the urb */ 1427 struct kref kref;

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.
