It looks as if Neil applied quite a few of them already, so I looked
at what was left...

I'm a little hesitant to just apply the whole kit-and-caboodle to
drm-misc-next since there are specific DRM trees for a bunch of them
and it would be better if they landed there. ...so I went through all
the patches that still applied to drm-misc-next, then used
'scripts/get_maintainer.pl --scm' to check if they were maintained
through drm-misc. That still left quite a few patches. I've applied
those ones and pushed to drm-misc-next:

callback returning void

The following ones appeared to apply to the top of drm-misc-next, but
I didn't apply them since get_maintainer didn't say they were part of
drm-misc-next:

drm/tiny: Convert to platform remove callback returning void
drm/tilcdc: Convert to platform remove callback returning void
drm/sprd: Convert to platform remove callback returning void
