That's unusual and seems >likely to break some systems that rely on exact clocking. I put this code to avoid overwrite BCLK value in TDM mode. BCLK is being configured by ' max98927_dai_tdm_slot'.

OK. Thanks. But I kept if statement on the modified version because it only have two cases, tdm and non-tdm.
