[ 11/47] media: s5p-fimc: Fix locking in subdev set_crop op

From: Greg KH
Date: Fri May 18 2012 - 19:06:02 EST


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

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

From: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx>

commit e985dbf7d93e2a3e114b4525413e50f83613e0cb upstream.

When setting TRY crop on the sub-device the mutex was erroneously acquired
rather than released on exit path. This bug is present in kernels starting
from v3.2.
