Luis Henriques Feb. 28, 2013, 2:43 p.m. -stable review patch.  If anyone has any objections, please let me know.


From: Denis Efremov <yefremov.denis@gmail.com>

commit f49a59c4471d81a233e09dda45187cc44fda009d upstream.

According to the other code in this driver and similar
code in rme96 it seems, that spin_lock_irq in
snd_rme32_capture_close function should be paired
with spin_unlock_irq.

Found by Linux Driver Verification project (linuxtesting.org).
