From faaa136bc7a4ed96ffe9585b495ec8bfac0032a8 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 21 Apr 2016 17:37:54 +0200 Subject: [PATCH] ALSA: pcxhr: Fix missing mutex unlock [ Upstream commit 67f3754b51f22b18c4820fb84062f658c30e8644 ] 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.
