ALSA: pcxhr: Fix missing mutex unlock
The commit [9bef72bdb26e: ALSA: pcxhr: Use nonatomic PCM ops] converted to non-atomic PCM ops, but shamelessly with an unbalanced mutex locking, which leads to the hangup easily. Fix it. Fixes: 9bef72bdb26e ('ALSA: pcxhr: Use nonatomic PCM ops') Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=116441 Cc: <stable@vger.kernel.org> # 3.18+ Signed-off-by: Takashi Iwai <tiwai@suse.de>
