Actually q6afe-dai does not seem to make use of the register number. The DAPM widgets all look like
SND_SOC_DAPM_AIF_IN("HDMI_RX", NULL, 0, 0, 0, 0), /* (wname, stname, wchan, wreg, wshift, winvert)
Wouldn't it be better to replace wreg = 0 with SND_SOC_NOPM in this case so the read/write won't happen at all?
Yes, if they are not used at all then that's what _NOPM is for.
