Fix commit: 0c0bf6318018 Serialize access to the list of attached child devices belonging to a wsmux. When invoking wsevsrc_* functions on a attached child device, underlying driver can sleep; this introduces a race where another thread is able to modify the list leading to all kinds of corruptions.
