Subject[PATCH 2/3] ASoC: tlv320aic32x4: Fix bdiv clock rate derivation
Date
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: 96c3bb00239d ("ASoC: tlv320aic32x4: Dynamically Determine Clocking")
