Subject: [154/289] ASoC: wm8961 - clear WM8961_MCLKDIV bit for freq <= 16500000

2.6.36-stable review patch.  If anyone has any objections, please let us know.

------------------

From: Axel Lin <axel.lin@...il.com>

commit 2f7dceeda4708f470fd927adb3861bd8ebbe2310 upstream.

MCLKDIV bit of Register 04h Clocking1:
	0 : Divide by 1
	1 : Divide by 2

Thus in the case of freq <= 16500000, we should clear MCLKDIV bit.
