Subject: [PATCH v4 00/12] AC97 device/driver model revamp
Hi Lars, Mark, Charles, Lee,
This is a minor revision after v3, mainly reviews from Takashi, Charles.
I did more extensive testing of load/unload of the whole serie, and apart from a
bug in wm97xx-core in touchscreen tree (for a which a patch will be sent apart),
it seems to work properly. I extracted the diff from the v3 of sound/ac97 which
is in [1] for easier spotting of what has globally changed.
I would still need a review from you, Lee, for the mfd patch (patch 6/12).
Happy review.
