3.5.7.2 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sylwester Nawrocki <s.nawrocki@samsung.com>

commit ddc43d6dc7df0849fe41b91460fa76145cf87b67 upstream.

Use uninterruptible mutex_lock in the release() file op to make
sure all resources are properly freed when a process is being
terminated. Returning -ERESTARTSYS has no effect for a terminating
process and this may cause driver resources not to be released.
This patch is required for stable kernels v3.5+.
