[PATCH 3.14 052/114] ASoC: pcm: fix dpcm_path_put in dpcm runtime update

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

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

------------------

From: Qiao Zhou <zhouqiao@marvell.com>

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.
