Subject: [ 14/28] ASoC: wm8960: Fix PLL register writes

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

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

From: Mike Dyer <mike.dyer@...soft.co.uk>

commit 85fa532b6ef920b32598df86b194571a7059a77c upstream.

Bit 9 of PLL2,3 and 4 is reserved as '0'. The 24bit fractional part
should be split across each register in 8bit chunks.
