Subject: ASoC: pcm: allow backend hardware to be freed in pause state
From: Patrick Lai <[email protected]>
commit 08b27848da620f206a8b6d80f26184485dd7aa40 upstream.
When front-end PCM session is in paused state, back-end
PCM session will be put in paused state as well if given
front-end PCM session is the only client of given back-end.
Then, application closes front-end PCM session, DPCM
framework will not allow back-end enters HW_FREE state
so back-end will never get shutdown completely.
