522 * of which the first 33 / 25 clocks HSYNC must be held active. This
523 * has to be configured in CR[HW]. 1 pixel equals 2 clock periods.
524 * This gives CR[HW] = 16 / 12, VPR[HVP] = 138 / 144, which gives
525 * exactly 858 - 138 = 864 - 144 = 720! We call the out-of-display area,
526 * beyond DSR, specified on the left and top by the VPR register "black
527 * pixels" and out-of-image area (DPR) "background pixels." We fix VPR
528 * at 138 / 144 : 20, because that's the HSYNC timing, that our first
529 * client requires, and that's exactly what leaves us 720 pixels for the
530 * image; we leave VPR[VVP] at default 20 for now, because the client
531 * doesn't seem to have any special requirements for it. Otherwise we
532 * could also set it to max - 240 = 22 / 72. Thus VPR depends only on
533 * the selected standard, and DPR and DSR are selected according to
534 * cropping. Q: how does the client detect the first valid line? Does
535 * HSYNC stay inactive during invalid (black) lines?

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

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.
