ASoC: WM8990: Fix kcontrol's private value use in put callback
Jarkko Nikula [Fri, 6 Feb 2009 10:01:05 +0000 (12:01 +0200)]
Function wm899x_outpga_put_volsw_vu misuses the kcontrol's private value
by still accessing it as bitfields even SOC_SINGLE_VALUE constructs it
as a pointer into struct soc_mixer_control after the commit
4eaa9819dc08d7bfd1065ce530e31b18a119dcaf.

This is very similar fix than fix to TLV320AIC3X codec made by
Eero Nurkkala <ext-eero.nurkkala@nokia.com>. This fix is compile tested
only.
