[alsa-devel] [PATCH 1/2] swarm_cs4297: Provide definitions for AC97 registers
This patch removes the last usage of linux/ac97_codec.h by re-defining used AC97 registers. We can't use sound/ac97_codec.h here, since it is an OSS driver.
Not even compilation tested.

I tried the cross-compile and looks OK, so applied both patches now.
