* struct class_device - class devices
* @class: pointer to the parent class for this class device. This is required.
* @devt: for internal use by the driver core only.
* @node: for internal use by the driver core only.
* @kobj: for internal use by the driver core only.
* @devt_attr: for internal use by the driver core only.
* @dev: if set, a symlink to the struct device is created in the sysfs
* directory for this struct class device.
* @class_data: pointer to whatever you want to store here for this struct
* class_device. Use class_get_devdata() and class_set_devdata() to get and
* set this pointer.
* @parent: pointer to a struct class_device that is the parent of this struct
* class_device. If NULL, this class_device will show up at the root of the
* struct class in sysfs (which is probably what you want to have happen.)
* @release: pointer to a release function for this struct class_device. If
* set, this will be called instead of the class specific release function.
* Only use this if you want to override the default release function, like
* when you are nesting class_device structures.
* @hotplug: pointer to a hotplug function for this struct class_device. If
* set, this will be called instead of the class specific hotplug function.
* Only use this if you want to override the default hotplug function, like
* when you are nesting class_device structures.
