-/**
- * struct device - The basic device structure
- * @parent: The device's "parent" device, the device to which it is attached.
- * In most cases, a parent device is some sort of bus or host
- * controller. If parent is NULL, the device, is a top-level device,
- * which is not usually what you want.
- * @p: Holds the private data of the driver core portions of the device.
- * See the comment of the struct device_private for detail.
- * @kobj: A top-level, abstract class from which other classes are derived.
- * @init_name: Initial name of the device.
- * @type: The type of device.
- * This identifies the device type and carries type-specific
- * information.
- * @mutex: Mutex to synchronize calls to its driver.
- * @bus: Type of bus device is on.
- * @driver: Which driver has allocated this
- * @platform_data: Platform data specific to the device.
- * Example: For devices on custom boards, as typical of embedded
- * and SOC based hardware, Linux often uses platform_data to point
- * to board-specific structures describing devices and how they
- * are wired. That can include what ports are available, chip
- * variants, which GPIO pins act in what additional roles, and so
- * on. This shrinks the "Board Support Packages" (BSPs) and
- * minimizes board-specific #ifdefs in drivers.
- * @driver_data: Private pointer for driver specific info.
- * @links: Links to suppliers and consumers of this device.
- * @power: For device power management.
- * See Documentation/driver-api/pm/devices.rst for details.
- * @pm_domain: Provide callbacks that are executed during system suspend,
- * hibernation, system resume and during runtime PM transitions
- * along with subsystem-level and driver-level callbacks.
- * @em_pd: device's energy model performance domain
- * @pins: For device pin management.
- * See Documentation/driver-api/pin-control.rst for details.
- * @msi: MSI related data
- * @numa_node: NUMA node this device is close to.
- * @dma_ops: DMA mapping operations for this device.
- * @dma_mask: Dma mask (if dma'ble device).
- * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all
- * hardware supports 64-bit addresses for consistent allocations
- * such descriptors.
- * @bus_dma_limit: Limit of an upstream bridge or bus which imposes a smaller
- * DMA limit than the device itself supports.
- * @dma_range_map: map for DMA memory ranges relative to that of RAM
- * @dma_parms: A low level driver may set these to teach IOMMU code about
- * segment limitations.
- * @dma_pools: Dma pools (if dma'ble device).
- * @dma_mem: Internal for coherent mem override.
- * @cma_area: Contiguous memory area for dma allocations
- * @dma_io_tlb_mem: Software IO TLB allocator. Not for driver use.
- * @dma_io_tlb_pools: List of transient swiotlb memory pools.
- * @dma_io_tlb_lock: Protects changes to the list of active pools.
- * @dma_uses_io_tlb: %true if device has used the software IO TLB.
- * @archdata: For arch-specific additions.
- * @of_node: Associated device tree node.
- * @fwnode: Associated device node supplied by platform firmware.
- * @devt: For creating the sysfs "dev".
- * @id: device instance
- * @devres_lock: Spinlock to protect the resource of the device.
- * @devres_head: The resources list of the device.
- * @class: The class of the device.
- * @groups: Optional attribute groups.
- * @release: Callback to free the device after all references have
- * gone away. This should be set by the allocator of the
- * device (i.e. the bus driver that discovered the device).
- * @iommu_group: IOMMU group the device belongs to.
- * @iommu: Per device generic IOMMU runtime data
- * @physical_location: Describes physical location of the device connection
- * point in the system housing.
- * @removable: Whether the device can be removed from the system. This
- * should be set by the subsystem / bus driver that discovered
- * the device.
- *
- * @offline_disabled: If set, the device is permanently online.
- * @offline: Set after successful invocation of bus type's .offline().
- * @of_node_reused: Set if the device-tree node is shared with an ancestor
- * device.
- * @state_synced: The hardware state of this device has been synced to match
- * the software state of this device by calling the driver/bus
- * sync_state() callback.
- * @can_match: The device has matched with a driver at least once or it is in
- * a bus (like AMBA) which can't check for matching drivers until
- * other devices probe successfully.
- * @dma_coherent: this particular device is dma coherent, even if the
- * architecture supports non-coherent devices.
- * @dma_ops_bypass: If set to %true then the dma_ops are bypassed for the
- * streaming DMA operations (->map_* / ->unmap_* / ->sync_*),
- * and optionall (if the coherent mask is large enough) also
- * for dma allocations. This flag is managed by the dma ops
- * instance from ->dma_supported.
- *
- * At the lowest level, every device in a Linux system is represented by an
- * instance of struct device. The device structure contains the information
- * that the device model core needs to model the system. Most subsystems,
- * however, track additional information about the devices they host. As a
- * result, it is rare for devices to be represented by bare device structures;
- * instead, that structure, like kobject structures, is usually embedded within
- * a higher-level representation of the device.

+/**
+ * struct device - The basic device structure
+ * @parent: The device's "parent" device, the device to which it is attached.
+ * In most cases, a parent device is some sort of bus or host
+ * controller. If parent is NULL, the device, is a top-level device,
+ * which is not usually what you want.
+ * @p: Holds the private data of the driver core portions of the device.
+ * See the comment of the struct device_private for detail.
+ * @kobj: A top-level, abstract class from which other classes are derived.
+ * @init_name: Initial name of the device.
+ * @type: The type of device.
+ * This identifies the device type and carries type-specific
+ * information.
+ * @mutex: Mutex to synchronize calls to its driver.
+ * @bus: Type of bus device is on.
+ * @driver: Which driver has allocated this
+ * @platform_data: Platform data specific to the device.
+ * Example: For devices on custom boards, as typical of embedded
+ * and SOC based hardware, Linux often uses platform_data to point
+ * to board-specific structures describing devices and how they
+ * are wired. That can include what ports are available, chip
+ * variants, which GPIO pins act in what additional roles, and so
+ * on. This shrinks the "Board Support Packages" (BSPs) and
+ * minimizes board-specific #ifdefs in drivers.
+ * @driver_data: Private pointer for driver specific info.
+ * @links: Links to suppliers and consumers of this device.
+ * @power: For device power management.
+ * See Documentation/driver-api/pm/devices.rst for details.
+ * @pm_domain: Provide callbacks that are executed during system suspend,
+ * hibernation, system resume and during runtime PM transitions
+ * along with subsystem-level and driver-level callbacks.
+ * @em_pd: device's energy model performance domain
+ * @pins: For device pin management.
+ * See Documentation/driver-api/pin-control.rst for details.
+ * @msi: MSI related data
+ * @numa_node: NUMA node this device is close to.
+ * @dma_ops: DMA mapping operations for this device.
+ * @dma_mask: Dma mask (if dma'ble device).
+ * @coherent_dma_mask: Like dma_mask, but for alloc_coherent mapping as not all
+ * hardware supports 64-bit addresses for consistent allocations
+ * such descriptors.
+ * @bus_dma_limit: Limit of an upstream bridge or bus which imposes a smaller
+ * DMA limit than the device itself supports.
+ * @dma_range_map: map for DMA memory ranges relative to that of RAM
+ * @dma_parms: A low level driver may set these to teach IOMMU code about
+ * segment limitations.
+ * @dma_pools: Dma pools (if dma'ble device).
+ * @dma_mem: Internal for coherent mem override.
+ * @cma_area: Contiguous memory area for dma allocations
+ * @dma_io_tlb_mem: Software IO TLB allocator. Not for driver use.
+ * @dma_io_tlb_pools: List of transient swiotlb memory pools.
+ * @dma_io_tlb_lock: Protects changes to the list of active pools.
+ * @dma_uses_io_tlb: %true if device has used the software IO TLB.
+ * @archdata: For arch-specific additions.
+ * @of_node: Associated device tree node.
+ * @fwnode: Associated device node supplied by platform firmware.
+ * @devt: For creating the sysfs "dev".
+ * @id: device instance
+ * @devres_lock: Spinlock to protect the resource of the device.
+ * @devres_head: The resources list of the device.
+ * @class: The class of the device.
+ * @groups: Optional attribute groups.
+ * @release: Callback to free the device after all references have
+ * gone away. This should be set by the allocator of the
+ * device (i.e. the bus driver that discovered the device).
+ * @iommu_group: IOMMU group the device belongs to.
+ * @iommu: Per device generic IOMMU runtime data
+ * @physical_location: Describes physical location of the device connection
+ * point in the system housing.
+ * @removable: Whether the device can be removed from the system. This
+ * should be set by the subsystem / bus driver that discovered
+ * the device.
+ *
+ * @offline_disabled: If set, the device is permanently online.
+ * @offline: Set after successful invocation of bus type's .offline().
+ * @of_node_reused: Set if the device-tree node is shared with an ancestor
+ * device.
+ * @state_synced: The hardware state of this device has been synced to match
+ * the software state of this device by calling the driver/bus
+ * sync_state() callback.
+ * @can_match: The device has matched with a driver at least once or it is in
+ * a bus (like AMBA) which can't check for matching drivers until
+ * other devices probe successfully.
+ * @dma_coherent: this particular device is dma coherent, even if the
+ * architecture supports non-coherent devices.
+ * @dma_ops_bypass: If set to %true then the dma_ops are bypassed for the
+ * streaming DMA operations (->map_* / ->unmap_* / ->sync_*),
+ * and optionall (if the coherent mask is large enough) also
+ * for dma allocations. This flag is managed by the dma ops
+ * instance from ->dma_supported.
+ *
+ * At the lowest level, every device in a Linux system is represented by an
+ * instance of struct device. The device structure contains the information
+ * that the device model core needs to model the system. Most subsystems,
+ * however, track additional information about the devices they host. As a
+ * result, it is rare for devices to be represented by bare device structures;
+ * instead, that structure, like kobject structures, is usually embedded within
+ * a higher-level representation of the device.
