Nice, thanks for the pointers.

Of course.

Good luck testing every kernel release :)

Perhaps you might want to automate this with a test against the
kernel-of-the-day once the driver makes it into mainline?  I know some
people who are working on a kernel tinderbox that this kind of effort
would tie nicely into.

That's a good goal, sounds like you are well on your way.  Now if only
everyone would have test suites for drivers...
