Subject: [PATCH v3 00/12] AC97 device/driver model revamp

Hi Lars, Mark, Charles, Lee,

This is a resend of the v2, with patch 1 added (forgotten in v2). Patch 12 was
slightly modified after module unloading tests, and Dmitry acks were added.

This serie has been stalled for almost one year, as I wasn't feeling that
well lately. I'm quite better now, so let's get back to it.

The following sentences is a what was already said in v2.

As it's been so long since the last review, I basically withdrew all my former
objections and took into account all remarks regardless of my own
judgement. This is especially the case with Lars's review on the bus code, where
I tried to address all his comments.

For this next round, let's sum up what happened :
 - I rebased against latest Linus's tree
   => as Lars had made ports to regmap of several impacted wm97xx drivers, all
   the better for me.
   
 - ALSA: ac97: add an ac97 bus
   => this addresses Lars's comments
   => history : https://patchwork.kernel.org/patch/9398229/
   => there is one remark which was left out, the drop of the table
      ac97_controller->codecs. The reason is that there are traversals required
      in the bus scan and controller removal, and the code is way simpler with a
      table, and the data structure very compact.
   
 - Input: wm97xx: split out touchscreen registering
   => Charles's comment taken into account
   => history: http://https://patchwork.kernel.org/patch/9398223/

Have a happy review.
