From 2f8e6140bb6ad439ec3e32e4bd4e06af9c3f43cd Mon Sep 17 00:00:00 2001 From: Patrick Lai Date: Sat, 31 Dec 2016 22:44:39 -0800 Subject: ASoC: dpcm: Avoid putting stream state to STOP when FE stream is paused [ Upstream commit 9f169b9f52a4afccdab7a7d2311b0c53a78a1e6b ] When multiple front-ends are using the same back-end, putting state of a front-end to STOP state upon receiving pause command will result in backend stream getting released by DPCM framework unintentionally. In order to avoid backend to be released when another active front-end stream is present, put the stream state to PAUSED state instead of STOP state.
