Yes, please take this one now.  We can build on it from there.

I had a meeting yesterday with a lot of rust kernel and userspace people
at Microsoft and talked a bunch about this and how to move forward.  I
think we need to take much smaller "steps" and even encourage most
drivers to start out as a mix of c and rust as there is no real
"requirement" that a driver be "pure" rust at all.  This should both
make the interface logic simpler to start with, AND provide a base so
that people can just write the majority of their driver logic in rust,
which is where the language "safety" issues are most needed, not in the
lifecycle rules involving the internal driver model infrastructure.

Anyway, that's all hand-wavy right now, sorry, to get back to the point
here, again, let's take this, which will allow the firmware bindings to
be resubmitted and hopefully accepted, and we can move forward from
there to "real" things like a USB or PCI or even platform device and
driver binding stuff.
