Defacto dri-devel folks are maintainer component.c, but also I'm not
aware of anything missing there?

There has been discussions that in various drm subsystems like
drm_bridge or drm_panel a few things are missing, which prevent
drivers from moving _away_ from component.c to the more specific
solutions for panel/bridges. But nothing that's preventing them from
using component.c itself.

I'm happy to merge a MAINTAINERS patch to clarify the situation if
that's needed.
