Subject[PATCH 3.12 28/72] mfd: wm5110: Add register patch for rev E and above
Date
From: Charles Keepax <ckeepax@opensource.wolfsonmicro.com>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit 81207880cef207cd89db863f9aa1d65f22b4f2a2 upstream.

Add a register patch for rev E and above that configures the location of
some write sequences to assist with the headphone enables.
