The patch

ALSA: ac97: split out the generic ac97 registers

has been applied to the asoc tree at

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ALSA: ac97: split out the generic ac97 registers

Split out from the ac97_codec.h the ac97 generic registers, which can be
used by a codec, typically a generic ac97 codec, and by the ac97 bus, to
scan an ac97 AC-Link.

This split encompasses all the AC97 standard registers, but not the
codec specific ones.

In order to have a clean split between former ac97 bus implementation
and the new coming one in sound/ac97, it is safer to not include any
former ac97 includes, excepting in sound/ac97/compat.c.

Amongst the thing to isolate :
- don't have the struct snd_ac97 in sound/ac97/* (except compat.c) to not
be "fooled" by a definition which would come with ac97_codec.h by
"chance".
- don't have to have snd_a97_*() functions, as they rely on struct
snd_ac97.
- don't want the struct snd_ac97_bus_ops, there is a new one
