They can, but I've explicitly asked Vinod to ack them so that they can
go in with the rest of the series through DRM.

They also fix a regression that came in through DRM in 6.8-rc1 (the
bridge rework which started registering child devices) so it makes sense
to also route the fix the same way. And to do it for this cycle.

You have Bjorn's ack. He's reviewed all the patches for this purpose and
we discussed this in person two days ago.

And, again, this has to go in for *this* cycle. You broke the display on
the X13s and other machines so this cannot wait for 6.9.
