Commit '166a34d ASoC: ab8500: Fix invalid cast to long pointer' rather carelessly converts find_next_bit() to fls() (find last bit set), which are not the same.
Although this implementation may not be portable, the alternative breaks audio on anything using the AB8500 CODEC, which is a much greater evil. Besides, this driver will never run on anything else.
