+Subject: [PATCH 1268/1295] ASoC: DACplusADCPro - 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.
+
+Problem appears only on PI5 as on the former PIs the I2S module
+did simply run at fixed 64x rate.
