From 8bcead1f0d58259db8ddabd919008637fc4299d0 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?=EC=9D=B4=EA=B2=BD=ED=83=9D?= Date: Wed, 1 Apr 2020 10:04:21 +0900 Subject: ASoC: dpcm: allow start or stop during pause for backend commit 21fca8bdbb64df1297e8c65a746c4c9f4a689751 upstream. soc_compr_trigger_fe() allows start or stop after pause_push. In dpcm_be_dai_trigger(), however, only pause_release is allowed command after pause_push. So, start or stop after pause in compress offload is always returned as error if the compress offload is used with dpcm. To fix the problem, SND_SOC_DPCM_STATE_PAUSED should be allowed for start or stop command.
