From: 이경택 <gt82.lee@samsung.com>
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.
