Subject: ASoC: core: remove codec from list if registration failed
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e1328a832c7eeeb4dd3c3666605717c555de9e83;p=openwrt%2Fstaging%2Fblogic.git

ASoC: core: remove codec from list if registration failed

Current snd_soc_register_codec() adds codec to list, and calls
snd_soc_register_dais().
But, this listed codec should be removed if dais registration
was failed.
