Subject: [PATCH 02/10] ALSA: pcsp: Fix initialization with nopcm=1
Date: Tue, 29 Oct 2013 17:00:25 +0100 [thread overview]
Message-ID: <1383062433-9388-3-git-send-email-tiwai@suse.de> (raw)
In-Reply-To: <1383062433-9388-1-git-send-email-tiwai@suse.de>
When nopcm=1 is set, some initializations based on hrtimer resolution
might be bogus because the driver checks the resolution only when
nopcm=0. Simply get the resolution always at first for fixing the
bug.
Spotted by coverity CID 139740.
