Subject: [PATCH] ALSA: pcxhr: Fix missing mutex unlock
Date: Thu, 21 Apr 2016 17:40:51 +0200 [thread overview]
Message-ID: <1461253251-21005-1-git-send-email-tiwai@suse.de> (raw)
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+
