Well, that doesn't work because I won't be reading mail that week,
and I'll probably simply ignore the excessive backlog when I do
start reading mail again.

Correct, and unless you wish me to do the work for you (in which case
you can pay me) nothing is going to change on that front!  Seriously,
please do not expect me to add support for platforms I don't have
access to.  I'm just a volunteer for this, probably the same as you.

I don't think we ended up with an answer for that problem.  I don't
see that dropping the requested interrupt, using the GPIO, and then
re-requesting the interrupt is an option - how do we handle a failure
to re-request the interrupt?  Do we just ignore the error, or let DRM
stop working properly?

In any case, I don't have a working HDMI CEC-compliant setup anymore,
(no TV, just a HDMI monitor now) so I would rather _not_ change the
driver from its known-to-be-working state.
