Bagas, thx again for your efforts, much appreciated. But I guess for drm
drivers that have a line like

B: https://gitlab.freedesktop.org/drm/[...]

in MAINTAINERS (which includes all the popular drm drivers) this just
creates a lot of confusion for everyone, as one issue will likely end up
being discussed in two or three places in parallel (bugzilla,
freedesktop, email). Better tell reporters to move their issue to the
freedesktop drm tracker and close the ticket in bugzilla. And don't get
regzbot involved, as it for now it sadly is unable to monitor the
freedesktop drm tracker (sooner or later I'll fix that, but for now it's
a blind spot :-/).

Pretty sure none of the DRM developers will disagree, but if I'm wrong,
please holler.

Side note: that currently does not work with regzbot. :-/ Whatever, I'll
remove it from the tracking due to above reasons:

#regzbot inconclusive: sadly not tracked for now

Ciao, Thorsten
