It is called at soc-core and soc-pcm. soc-pcm is controlling it for activate DAI. soc-core is controlling it for whole system (= suspend/resume/probe/poweroff). If we focus to soc-core side, it need to care about BIAS level. Then, snd_soc_suspend() only is controlling it by Component base (a). Other functions are DAI base (b). (a) pinctrl_pm_select_xxx(component->dev, xxx); (b) pinctrl_pm_select_xxx(dai->dev, xxx); Because of these unbalance, the code is confusable. Here, dai->dev and component->dev are same pointer. Thus, we can replace it component base. One note here is that it cared DAI (= CPU/Codec) pin before this patch, after this patch, it cares Component (= CPU/Codec/Platform) pin.
