If parent is NULL, the device, is a top-level device, 714 * which is not usually what you want. 715 * @p: Holds the private data of the driver core portions of the device. 716 * See the comment of the struct device_private for detail. 717 * @kobj: A top-level, abstract class from which other classes are derived. 718 * @init_name: Initial name of the device. 719 * @type: The type of device. 720 * This identifies the device type and carries type-specific 721 * information. 722 * @mutex: Mutex to synchronize calls to its driver. 723 * @bus: Type of bus device is on. 724 * @driver: Which driver has allocated this 725 * @platform_data: Platform data specific to the device. 726 * Example: For devices on custom boards, as typical of embedded 727 * and SOC based hardware, Linux often uses platform_data to point 728 * to board-specific structures describing devices and how they 729 * are wired. That can include what ports are available, chip 730 * variants, which GPIO pins act in what additional roles, and so 731 * on. This shrinks the "Board Support Packages" (BSPs) and 732 * minimizes board-specific #ifdefs in drivers. 733 * @driver_data: Private pointer for driver specific info. 734 * @power: For device power management. 735 * See Documentation/power/devices.txt for details. 736 * @pm_domain: Provide callbacks that are executed during system suspend, 737 * hibernation, system resume and during runtime PM transitions 738 * along with subsystem-level and driver-level callbacks. 739 * @pins: For device pin management. 740 * See Documentation/pinctrl.txt for details. 741 * @msi_list: Hosts MSI descriptors 742 * @msi_domain: The generic MSI domain this device is using. 743 * @numa_node: NUMA node this device is close to. 744 * @dma_mask: Dma mask (if dma'ble device). 745 * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all 746 * hardware supports 64-bit addresses for consistent allocations 747 * such descriptors. 748 * @dma_pfn_offset: offset of DMA memory range relatively of RAM 749 * @dma_parms: A low level driver may set these to teach IOMMU code about 750 * segment limitations. 751 * @dma_pools: Dma pools (if dma'ble device). 752 * @dma_mem: Internal for coherent mem override. 753 * @cma_area: Contiguous memory area for dma allocations 754 * @archdata: For arch-specific additions. 755 * @of_node: Associated device tree node. 756 * @fwnode: Associated device node supplied by platform firmware. 757 * @devt: For creating the sysfs "dev". 758 * @id: device instance 759 * @devres_lock: Spinlock to protect the resource of the device. 760 * @devres_head: The resources list of the device. 761 * @knode_class: The node used to add the device to the class list. 762 * @class: The class of the device. 763 * @groups: Optional attribute groups. 764 * @release: Callback to free the device after all references have 765 * gone away. This should be set by the allocator of the 766 * device (i.e. the bus driver that discovered the device). 767 * @iommu_group: IOMMU group the device belongs to. 768 * 769 * @offline_disabled: If set, the device is permanently online. 770 * @offline: Set after successful invocation of bus type's .offline(). 771 * 772 * At the lowest level, every device in a Linux system is represented by an 773 * instance of struct device. The device structure contains the information 774 * that the device model core needs to model the system. Most subsystems, 775 * however, track additional information about the devices they host. As a 776 * result, it is rare for devices to be represented by bare device structures; 777 * instead, that structure, like kobject structures, is usually embedded within 778 * a higher-level representation of the device. 779 */ 780 struct device { 781 struct device *parent; 782 783 struct device_private *p; 784 785 struct kobject kobj; 786 const char *init_name; /* initial name of the device */ 787 const struct device_type *type; 788 789 struct mutex mutex; /* mutex to synchronize calls to 790 * its driver. 791 */ 792 793 struct bus_type *bus; /* type of bus device is on */ 794 struct device_driver *driver; /* which driver has allocated this 795 device */ 796 void *platform_data; /* Platform specific data, device 797 core doesn't touch it */ 798 void *driver_data; /* Driver data, set and get with 799 dev_set/get_drvdata */ 800 struct dev_pm_info power; 801 struct dev_pm_domain *pm_domain; 802 803 #ifdef CONFIG_GENERIC_MSI_IRQ_DOMAIN 804 struct irq_domain *msi_domain; 805 #endif 806 #ifdef CONFIG_PINCTRL 807 struct dev_pin_info *pins; 808 #endif 809 #ifdef CONFIG_GENERIC_MSI_IRQ 810 struct list_head msi_list; 811 #endif 812 813 #ifdef CONFIG_NUMA 814 int numa_node; /* NUMA node this device is close to */ 815 #endif 816 u64 *dma_mask; /* dma mask (if dma'able device) */ 817 u64 coherent_dma_mask;/* Like dma_mask, but for 818 alloc_coherent mappings as 819 not all hardware supports 820 64 bit addresses for consistent 821 allocations such descriptors. */ 822 unsigned long dma_pfn_offset; 823 824 struct device_dma_parameters *dma_parms; 825 826 struct list_head dma_pools; /* dma pools (if dma'ble) */ 827 828 struct dma_coherent_mem *dma_mem; /* internal for coherent mem 829 override */ 830 #ifdef CONFIG_DMA_CMA 831 struct cma *cma_area; /* contiguous memory area for dma 832 allocations */ 833 #endif 834 /* arch specific additions */ 835 struct dev_archdata archdata; 836 837 struct device_node *of_node; /* associated device tree node */ 838 struct fwnode_handle *fwnode; /* firmware device node */ 839 840 dev_t devt; /* dev_t, creates the sysfs "dev" */ 841 u32 id; /* device instance */ 842 843 spinlock_t devres_lock; 844 struct list_head devres_head; 845 846 struct klist_node knode_class; 847 struct class *class; 848 const struct attribute_group **groups; /* optional groups */ 849 850 void (*release)(struct device *dev); 851 struct iommu_group *iommu_group; 852 853 bool offline_disabled:1; 854 bool offline:1; 855 }; 856 857 static inline struct device *kobj_to_dev(struct kobject *kobj) 858 { 859 return container_of(kobj, struct device, kobj); 860 } 861 862 /* Get the wakeup routines, which depend on struct device */ 863 #include <linux/pm_wakeup.h> 864 865 static inline const char *dev_name(const struct device *dev) 866 { 867 /* Use the init name until the kobject becomes available */ 868 if (dev->init_name) 869 return dev->init_name; 870 871 return kobject_name(&dev->kobj); 872 } 873 874 extern __printf(2, 3) 875 int dev_set_name(struct device *dev, const char *name, ...); 876 877 #ifdef CONFIG_NUMA 878 static inline int dev_to_node(struct device *dev) 879 { 880 return dev->numa_node; 881 } 882 static inline void set_dev_node(struct device *dev, int node) 883 { 884 dev->numa_node = node; 885 } 886 #else 887 static inline int dev_to_node(struct device *dev) 888 { 889 return -1; 890 } 891 static inline void set_dev_node(struct device *dev, int node) 892 { 893 } 894 #endif 895 896 static inline struct irq_domain *dev_get_msi_domain(const struct device *dev) 897 { 898 #ifdef CONFIG_GENERIC_MSI_IRQ_DOMAIN 899 return dev->msi_domain; 900 #else 901 return NULL; 902 #endif 903 } 904 905 static inline void dev_set_msi_domain(struct device *dev, struct irq_domain *d) 906 { 907 #ifdef CONFIG_GENERIC_MSI_IRQ_DOMAIN 908 dev->msi_domain = d; 909 #endif 910 } 911 912 static inline void *dev_get_drvdata(const struct device *dev) 913 { 914 return dev->driver_data; 915 } 916 917 static inline void dev_set_drvdata(struct device *dev, void *data) 918 { 919 dev->driver_data = data; 920 } 921 922 static inline struct pm_subsys_data *dev_to_psd(struct device *dev) 923 { 924 return dev ?

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.
