-/**
- * struct bus_type - The bus type of the device
- *
- * @name: The name of the bus.
- * @dev_name: Used for subsystems to enumerate devices like ("foo%u", dev->id).
- * @dev_root: Default device to use as the parent.
- * @bus_groups: Default attributes of the bus.
- * @dev_groups: Default attributes of the devices on the bus.
- * @drv_groups: Default attributes of the device drivers on the bus.
- * @match: Called, perhaps multiple times, whenever a new device or driver
- * is added for this bus. It should return a positive value if the
- * given device can be handled by the given driver and zero
- * otherwise. It may also return error code if determining that
- * the driver supports the device is not possible. In case of
- * -EPROBE_DEFER it will queue the device for deferred probing.
- * @uevent: Called when a device is added, removed, or a few other things
- * that generate uevents to add the environment variables.
- * @probe: Called when a new device or driver add to this bus, and callback
- * the specific driver's probe to initial the matched device.
- * @sync_state: Called to sync device state to software state after all the
- * state tracking consumers linked to this device (present at
- * the time of late_initcall) have successfully bound to a
- * driver. If the device has no consumers, this function will
- * be called at late_initcall_sync level. If the device has
- * consumers that are never bound to a driver, this function
- * will never get called until they do.
- * @remove: Called when a device removed from this bus.
- * @shutdown: Called at shut-down time to quiesce the device.
- *
- * @online: Called to put the device back online (after offlining it).
- * @offline: Called to put the device offline for hot-removal. May fail.
- *
- * @suspend: Called when a device on this bus wants to go to sleep mode.
- * @resume: Called to bring a device on this bus out of sleep mode.
- * @num_vf: Called to find out how many virtual functions a device on this
- * bus supports.
- * @dma_configure: Called to setup DMA configuration on a device on
- * this bus.
- * @pm: Power management operations of this bus, callback the specific
- * device driver's pm-ops.
- * @iommu_ops: IOMMU specific operations for this bus, used to attach IOMMU
- * driver implementations to a bus and allow the driver to do
- * bus-specific setup
- * @p: The private data of the driver core, only the driver core can
- * touch this.
- * @lock_key: Lock class key for use by the lock validator
- * @need_parent_lock: When probing or removing a device on this bus, the
- * device core should lock the device's parent.
- *
- * A bus is a channel between the processor and one or more devices. For the
- * purposes of the device model, all devices are connected via a bus, even if
- * it is an internal, virtual, "platform" bus. Buses can plug into each other.
- * A USB controller is usually a PCI device, for example. The device model
- * represents the actual connections between buses and the devices they control.
- * A bus is represented by the bus_type structure. It contains the name, the
- * default attributes, the bus' methods, PM operations, and the driver core's
- * private data.

- * @probe_type: Type of the probe (synchronous or asynchronous) to use.
- * @of_match_table: The open firmware table.
- * @acpi_match_table: The ACPI match table.
- * @probe: Called to query the existence of a specific device,
- * whether this driver can work with it, and bind the driver
- * to a specific device.
- * @sync_state: Called to sync device state to software state after all the
- * state tracking consumers linked to this device (present at

- * @remove: Called when the device is removed from the system to
- * unbind a device from this driver.
- * @shutdown: Called at shut-down time to quiesce the device.
- * @suspend: Called to put the device to sleep mode. Usually to a
- * low power state.
- * @resume: Called to bring a device from sleep mode.
- * @groups: Default attributes that get created by the driver core
- * automatically.
- * @pm: Power management operations of the device which matched
- * this driver.
- * @coredump: Called when sysfs entry is written to. The device driver
- * is expected to call the dev_coredump API resulting in a
- * uevent.
- * @p: Driver core's private data, no one other than the driver
- * core can touch this.
- *
- * The device driver-model tracks all of the drivers known to the system.
- * The main reason for this tracking is to enable the driver core to match

- * system, however, a number of other things become possible. Device drivers
- * can export information and configuration variables that are independent
