ASoC: tlv320aic32x4: Fix bdiv clock rate derivation (40b37136) · Commits · 戴 / test

Current code expects a single channel to be always used. Fix this situation by forwarding the number of channels used. Then fix the derivation of the bdiv clock rate. Fixes: ("ASoC: tlv320aic32x4: Dynamically Determine Clocking") Suggested-by:
