By his own account, he already has "all hands full replacing him [Alex]",
explicitly asked Daniel to merge an amdgpu patch through drm-misc-next for
this reason and lacks permission to update branches in Alex' repo on fdo:
"One lesson learned from the past week is that Alex needs to stop using
his personal repository on fdo.
We were asked a couple of times if I couldn't update a branch there from
different directions, which we obviously can't do."

Well, it wouldn't be nice towards users affected by the same issue
who may waste time with bisecting to just sit on a fix twiddling thumbs.
