ASoC: Factor out shared code from WM8993
Mark Brown [Wed, 29 Jul 2009 20:21:49 +0000 (21:21 +0100)]
The WM8993 analogue control is shared with other devices in the same
product line.  Since this is a very substantial proportion of the
driver move the definitions of these controls into a new wm_hubs module
which allows them to be shared between the two.
