Yeah, I suppose that would work, though it would require a bit of
research. Some other things have popped onto my plate recently, but
for now I'm going to focus on seeing how much of the drivers can get
their shutdown fixed. When that stalls out then we can see if we can
unblock some of the panels by digging into which DRM drivers they're
used with.

Also, as my proposal in the cover letter [1], I'm leaving a breadcrumb
here that I landed the first 3 patches in this series just to get them
out of the way. Those 3 patches didn't depend on the resolution of the
issues discussed here.
