3.13.11-ckt15 -stable review patch. If anyone has any objections, please let
me know.
------------------
From: Sakari Ailus <sakari.ai...@linux.intel.com>
commit f85698cd296f08218a7750f321e94607da128600 upstream.
The mutex does not serialise anything in this case but avoids a lockdep
warning from the control framework.
