From: Charles Keepax <ckeepax@xxxxxxxxxxxxxxxxxxxxxxxxxxx>
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.
