[PATCH 2/3] ASoC: tlv320aic32x4: Fix bdiv clock rate derivation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
