It's the same as for any other subsystem:
- don't base your stuff on top of random other trees
- except when you have a very specific excuse (i.e. functional
conflict with stuff in drm-next or something like that), use a release
tag from Linus' tree as your baseline

And when generating the pull, actually generate the pull against the
target tree/branch (drm-fixes or drm-next), not something else.
