Might be better to split this into an arch/arm patch and a sound/soc
patch - they don't appear to depend on each other so it'd ease merging.

This one needs a bit more explanation - why are you changing the AC97
slot?  Is this a general problem with the S3C AC97 controller?  It'd
also be better to use the symbolic register name rather than a number.
