Subject: [PATCH 44/93] clk: wm831x: Initialise wm831x pointer on init

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

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

From: Mark Brown <broonie@...aro.org>

commit 08442ce993deeb15a070c14cc3f3459e87d111e0 upstream.

Otherwise any attempt to interact with the hardware will crash. This is
what happens when drivers get written blind.
