From: Lu Guanqun Date: Wed, 6 Apr 2011 15:25:21 +0000 (+0800) Subject: ASoC: fix config error path X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c51def659870d25c735a9e06648e560ab39dbbb6;p=openwrt%2Fstaging%2Fblogic.git ASoC: fix config error path initialize ret to invalid value so that when we reach the config error path in soc_pcm_open, it will return the correct error code. without this patch, though config error path is executed, soc_pcm_open will return 0 in snd_pcm_open_substream and then cause double release of substream.
