7 A device class describes a type of device, like an audio or network
13 Each device class defines a set of semantics and a programming interface
14 that devices of that class adhere to. Device drivers are the
24 The device class structure looks like::
30 See the kerneldoc for the struct class.
32 A typical device class definition would look like::
40 Each device class structure should be exported in a header file so it
51 As devices are bound to drivers, they are added to the device class
57 The device is enumerated in the class. Each time a device is added to
58 the class, the class's devnum field is incremented and assigned to the
60 from the class and re-added, it will receive a different enumerated
63 The class is allowed to create a class-specific structure for the
66 There is no list of devices in the device class. Each driver has a
67 list of devices that it supports. The device class has a list of
68 drivers of that particular class. To access all of the devices in the
69 class, iterate over the device lists of each driver in the class.

148 When a device is added to a device class, the core attempts to add it
