The bridge maintainer is looking for new bridge maintainers (atm we have
only one, defacto), so for bridge driver patches I really don't think it's
a good idea to gate on that single bottle-neck. Infrastructure is a bit a
different thing.

Wahtever you feel like, just wanted to make sure you're not stuck
twiddling thumbs. The entire point of drm-misc is to facility mesh review
and maintainership, because the strict hierarchy just doesn't work for
smaller things. Exactly because you're always blocked on a bottleneck
somewhere.
