4.1-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ben Zhang <benzh@chromium.org> commit a6c2a32ac83567f15e9af3dcbc73148ce68b2ced upstream. The regmap_write in ssm4567_set_dai_fmt accidentally clears the TDM_BCLKS field which was set earlier by ssm4567_set_tdm_slot. This patch fixes it by using regmap_update_bits with proper mask.
