   4 Subject: [PATCH 1265/1295] ASoC: DACplus - fix 16bit sample support in clock
   5  consumer mode
   6
   7 The former code did not adjust the physical sample width when
   8 in clock consumer mode and has taken the fixed 32 bit default.
   9 This has caused the audio to be played at half its frequency due to
  10 the fixed bclk_ratio of 64.
