+Subject: [PATCH] ASoc: wm8731: add 32bit mode.
+
+commit cf5ef3a299ba32f6ac24c3c6ba18c1b7f1b5475f upstream.
+
+This patch adds 32 bit word capability to the wm8731 driver. The wm8731
+codec is capable of handling 32 bit word sizes, however that has not
+previously been activated in the codec driver.
