X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c1ccac415f7cb78f9f3709350f0eb60df775abdb;p=karo-tx-linux.git

ASoC: pcm: fix dpcm_path_put in dpcm runtime update

commit 7ed9de76ff342cbd717a9cf897044b99272cb8f8 upstream.

we need to release dapm widget list after dpcm_path_get in
soc_dpcm_runtime_update. otherwise, there will be potential memory
leak. add dpcm_path_put to fix it.
