245 * struct class_device - class devices
246 * @class: pointer to the parent class for this class device. This is required.
247 * @devt: for internal use by the driver core only.
248 * @node: for internal use by the driver core only.
249 * @kobj: for internal use by the driver core only.
250 * @groups: optional additional groups to be created
251 * @dev: if set, a symlink to the struct device is created in the sysfs
252 * directory for this struct class device.
253 * @class_data: pointer to whatever you want to store here for this struct
254 * class_device. Use class_get_devdata() and class_set_devdata() to get and
255 * set this pointer.
256 * @parent: pointer to a struct class_device that is the parent of this struct
257 * class_device. If NULL, this class_device will show up at the root of the
258 * struct class in sysfs (which is probably what you want to have happen.)
259 * @release: pointer to a release function for this struct class_device. If
260 * set, this will be called instead of the class specific release function.
261 * Only use this if you want to override the default release function, like
262 * when you are nesting class_device structures.
263 * @uevent: pointer to a uevent function for this struct class_device. If
264 * set, this will be called instead of the class specific uevent function.
265 * Only use this if you want to override the default uevent function, like
266 * when you are nesting class_device structures.
