Subject: ASoC: topology: free stream_name of dai_drv
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7b6f68a4df4df3a58e854d24da991640bd4d9590;p=linux.git

ASoC: topology: free stream_name of dai_drv

The stream_name is allocated by kstrdup. We have to free it when the
dai is removed or return from error.
