From: Qiao Zhou <zhouqiao@xxxxxxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.


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.
