I doubt that you need to use this mutex, as you're using atomics...

+	else
+		atomic_inc(&msg_queue->lat_list_cnt);

This branch (with the relevant appropriate changes) can be simplified as

	atomic_inc(&msg_queue->list_cnt[hardware_index]);

...where list_cnt is an array, and hardware_index is an enumeration.	

+	mutex_unlock(&msg_queue->list_cnt_mutex);

Same here.
