Sorry for not keeping up with things, but can you point to where this
was documented or what patch changed things so that these drivers went
through drm-misc? From the MAINTAINERS file I see commit 5a44d50f0072
("MAINTAINERS: Update drm-misc entry to match all drivers") and that
shows several of these drivers as "X:". As far as I can tell that
means that they _aren't_ handled by drm-misc, right? Maybe the
decision was made elsewhere and MAINTAINERS was just not updated, or
I'm not looking at the right place? I checked drm-misc-next and
drm/next and, for instance, "tegra" and "kmb" still show as excluded.
