From ab589fe38986d5d0feb1fff3a4c5a7bff5e64bc0 Mon Sep 17 00:00:00 2001 From: Cezary Rojewski Date: Mon, 26 Oct 2020 11:01:29 +0100 Subject: ASoC: pcm: DRAIN support reactivation [ Upstream commit 4c22b80f61540ea99d9b4af0127315338755f05b ] soc-pcm's dpcm_fe_dai_do_trigger() supported DRAIN commnad up to kernel v5.4 where explicit switch(cmd) has been introduced which takes into account all SNDRV_PCM_TRIGGER_xxx but SNDRV_PCM_TRIGGER_DRAIN. Update switch statement to reactive support for it. As DRAIN is somewhat unique by lacking negative/stop counterpart, bring behaviour of dpcm_fe_dai_do_trigger() for said command back to its pre-v5.4 state by adding it to START/RESUME/PAUSE_RELEASE group.
