ASoC: soc-pcm: care trigger rollback
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.
