Patches for fbdev drivers don't usually affect DRM but that's not the
case for patches to fbdev core and fbcon as you and others mentioned.

And how would people know which ones need to go through dri-devel ? Are
you planning to add another entry to MAINTAINERS for fbdev core/fbcon ?

In my opinion having fbdev patches in the dri-devel mailing list isn't
a big burden, but rather getting people to review and push say patches.

Since you are volunteering for the latter, that should improve things.

I still fail to see the benefit of doing that split, same for having a
separate fbdev tree. Using drm-misc only have advantages, among other
things providing redundancy in cases that a maintainer isn't available
for a period of time.
