	 * Since we use multi_cmd_pending for dmub command, the 2nd command is
	 * only assigned to store cursor attributes info.
	 * 1st command can view as 2 parts, 1st is for PSR/Replay data, the other
	 * is to store cursor position info.
	 *
	 * Command heaer type must be the same type if using  multi_cmd_pending.
	 * Besides, while process 2nd command in DMU, the sub type is useless.
	 * So it's meanless to pass the sub type header with different type.
