[PATCH 1/3] ASoC: Fix dependency on AC97_BUS

[Mark Brown]

When built with AC97 support the ASoC core depends on AC97_BUS so force
it to be available Kconfig.

[PATCH 2/3] ASoC: DAPM support for ADC on WM9713 PCM interface

[Mark Brown]

The stereo ADC in the WM9713 can be used to produce data for both the
standard AC97 interface and the additional voice PCM interface. Support
use on both by defining virtual ADCs tied to each accepting the output
from the actual ADCs.

[PATCH 3/3] ASoC: Add WM8750 SPI support

[Mark Brown]

Implement SPI support for WM8750, cut'n'pasting from the support for
WM8731 contributed by Cliff Cai and Alan Horstmann since the wire format
is the same for both codecs.

Also fix a cut'n'pasted comment in the I2C side of the driver (which was
clearly written in the same way) while we're at it.
