Sure, I'm fully aware of the issue.  The reason this is so painful to
work with is that AC'97 is just generally doing a really bad job of
using the driver model.

In my copious free time, but like I say trying to do this for 3.3 (you
only posted *after* the merge window opened) is just nuts and I'd rather
hope someone who cares about AC'97 systems will come forward and work on
it (having one would be a real bonus).  If people actually had problems
we were fixing that'd be one thing but if they do they're being
extremely quiet about it.

If it's code like the rtd devices which is reasonably sensible and
stable that's one thing but wading into code we know is fragile for
what's essentially a warning fix is completely disproportionate.  It's
not like we'd actually make a substantial improvement in the overall
code quality or robustness, if anyone's using AC'97 as a reference for
how to do this stuff they're going to have a bunch of other issues to
work through.
