645 The v4l2_ctrl_handler_log_status(ctrl_handler, prefix) can be used to dump the
656 different video nodes. You can do that by manually setting the ctrl_handler
661 control handler. You do that by simply setting the ctrl_handler field in
666 manually to add the subdev's control handler (sd->ctrl_handler) to the desired
