Subject: [46/70] ASoC: Correct WM8994 MICBIAS supply widget hookup

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

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

From: Mark Brown <broonie@...nsource.wolfsonmicro.com>

commit b793eb60a01d5b5e4aaeb2fbc2b036dec0d9f84d upstream.

The WM8994 and WM8958 series of devices have two MICBIAS supplies rather
than one, the current widget actually manages the microphone detection
control register bit (which is managed separately by the relevant API).

Fix this, hooking the relevant supplies up to the MICBIAS1 and MICBIAS2
widgets.
