[alsa-devel] [PATCH 2/3] swarm_cs4297: Rename AC97 registers to use sound/ac97_codec.h definitions

This patch removes the last usage of linux/ac97_codec.h
by renaming ac97 registers to use sound/ac97_codec.h definitions.
This will enable us to remove linux/ac97_codec.h.

Not even compilation tested.

Hi all,

This patch is important so we can remove linux/ac97_codec.h usage.
Since this driver is mips related, I can't test it until I install
a mips toolchain.
If someone can compile this for me, or even test it with real
hardware I think it would be better.
If not then I can install a mips toolchain and compile it myself,
but I won't be able to test it on real hardware.

This patch should be treated with carefully and be applied only
if someone manages to test it.

Regards,
Ezequiel.
