: Name of the class.
struct class - device classes : The module owner. : Default attributes of this class. : Default attributes of the devices belong to the class. : Default binary attributes of the devices belong to the class. : The kobject that represents this class and links it into the hierarchy. : Called when a device is added, removed from this class, or a few other things that generate uevents to add the environment variables. : Callback to provide the devtmpfs. : Called to release this class. : Called to release the device. : Used to put the device to sleep mode, usually to a low power state. : Used to bring the device from the sleep mode. : Callbacks so sysfs can detemine namespaces.
