Why not just make sc7280_snd_startup code like this:
static int sc7280_snd_startup(struct snd_pcm_substream *substream)
{
struct snd_soc_pcm_runtime *rtd = substream->private_data;
struct snd_soc_dai *cpu_dai = asoc_rtd_to_cpu(rtd, 0);
int ret = 0;
switch (cpu_dai->id) {
case MI2S_PRIMARY:
ret = sc7280_rt5682_init(rtd);
break;
default:
break;
}
return ret;
}
and sc7280_snd_shutdown with something similar
