From 78bfece00f4edb5d13e4e066c66e1c5903b69986 Mon Sep 17 00:00:00 2001

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.
