From 08b27848da620f206a8b6d80f26184485dd7aa40 Mon Sep 17 00:00:00 2001 From: Patrick Lai Date: Wed, 19 Dec 2012 19:36:02 -0800 Subject: ASoC: pcm: allow backend hardware to be freed in pause state 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.
