Subject: [PATCH 06/10] ALSA: ali5451: Drop unused variable
Date: Tue, 29 Oct 2013 17:00:29 +0100 [thread overview]
Message-ID: <1383062433-9388-7-git-send-email-tiwai@suse.de> (raw)
In-Reply-To: <1383062433-9388-1-git-send-email-tiwai@suse.de>
The variable runtime is never used, and this might be even a source of
NULL-dereference. Nothing better than killing it.
Spotted by coverity CID 100862.
Signed-off-by: Takashi Iwai <tiwai@suse.de>
