 /**
  * struct class - device classes
  * @name:       Name of the class.
  * @owner:      The module owner.
  * @class_attrs: Default attributes of this class.
  * @dev_groups: Default attributes of the devices that belong to the class.
  * @dev_kobj:   The kobject that represents this class and links it into the hierarchy.
  * @dev_uevent: Called when a device is added, removed from this class, or a
  *              few other things that generate uevents to add the environment
  *              variables.
  * @devnode:    Callback to provide the devtmpfs.
  * @class_release: Called to release this class.
  * @dev_release: Called to release the device.
  * @suspend:    Used to put the device to sleep mode, usually to a low power
  *              state.
  * @resume:     Used to bring the device from the sleep mode.
  * @ns_type:    Callbacks so sysfs can detemine namespaces.
  * @namespace:  Namespace of the device belongs to this class.
  * @pm:         The default device power management operations of this class.
  * @p:          The private data of the driver core, no one other than the
  *              driver core can touch this.
  *
  * A class is a higher-level view of a device that abstracts out low-level
  * implementation details. Drivers may see a SCSI disk or an ATA disk, but,
  * at the class level, they are all simply disks. Classes allow user space
  * to work with devices based on what they do, rather than how they are
  * connected or how they work.
