Subject: [PATCH 3.12 27/72] mfd: wm5110: Add register patch for rev D chip

From: Charles Keepax <ckeepax@...nsource.wolfsonmicro.com>

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

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

commit 02915661dbb91b25b621ab3f387ab55311bded7f upstream.

Evaluation of revision D of WM5110 suggests updates to the register
patch for optimal performance. For the sake of clarity rev C of the chip
does not require a register patch.
