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