[ 15/58] ALSA: rme32.c irq enabling after spin_lock_irq

From: Greg Kroah-Hartman

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


From: Denis Efremov <yefremov.denis@xxxxxxxxx>

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).
