soc_pcm_trigger() calls DAI/Component/Link trigger, but some of them might be failed. static int soc_pcm_trigger(...) { ... switch (cmd) { case SNDRV_PCM_TRIGGER_START: case SNDRV_PCM_TRIGGER_RESUME: case SNDRV_PCM_TRIGGER_PAUSE_RELEASE: ret = snd_soc_link_trigger(substream, cmd); if (ret < 0) break; (*) ret = snd_soc_pcm_component_trigger(substream, cmd); if (ret < 0) break; ret = snd_soc_pcm_dai_trigger(substream, cmd); break; case SNDRV_PCM_TRIGGER_STOP: case SNDRV_PCM_TRIGGER_SUSPEND: case SNDRV_PCM_TRIGGER_PAUSE_PUSH: ret = snd_soc_pcm_dai_trigger(substream, cmd); if (ret < 0) break; ret = snd_soc_pcm_component_trigger(substream, cmd); if (ret < 0) break; ret = snd_soc_link_trigger(substream, cmd); break; } ... } For example, if soc_pcm_trigger() failed at (*) point, we need to rollback previous succeeded trigger. This patch adds trigger mark for DAI/Component/Link, and do STOP if START/RESUME/PAUSE_RELEASE were failed. Because it need to use new rollback parameter, we need to modify DAI/Component/Link trigger functions in the same time.
