364 *	Optional cleanup called when reply data is no longer needed. Can be
365 *	used e.g. to free any additional data structures outside the main
366 *	structure which were allocated by ->prepare_data(). When processing
367 *	dump requests, ->cleanup() is called for each message.
368 * @set_validate:
369 *	Check if set operation is supported for a given device, and perform
370 *	extra input checks. Expected return values:
371 *	 - 0 if the operation is a noop for the device (rare)
372 *	 - 1 if operation should proceed to calling @set
