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
Yes. we can do as you suggested. Then Shall I do it as fix to a commit?
i.e. c5198db ASoC: qcom: Add driver support for ALC5682I-VS
