Subject: [ 28/53] [media] s5p-fimc: Fix locking in subdev set_crop op
Date: Fri, 18 May 2012 03:33:22 +0100 [thread overview]
Message-ID: <20120518023258.178779105@decadent.org.uk> (raw)
In-Reply-To: <20120518023254.339945758@decadent.org.uk>
3.2.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sylwester Nawrocki <s.nawrocki@samsung.com>
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.
