[PARTIAL PATCH] snd-hda-intel on Medion WIM2160

[Bernhard Rosenkraenzer <bero@arklinux.org>]

Hi,
On Medion WIM2160 notebooks (soundchip PCI ID 8086:27d8/17c0:4071), 
snd-hda-intel loads and everything acts like it's working, but there's no 
sound. The master volume is muted and there's no way to unmute it.

The patch below fixes it, but unfortunately, Medion MD2 uses the same PCI 
(and subvendor/subdevice) ID -- so the patch quite likely breaks Medion MD2 
support.

WIM2160's soundchip has revision ID 02 - if MD2 uses something else, maybe 
that can be used to identify them and do the right thing. (I don't have an 
MD2...).
