Sure, I guess I should have clarified this with "If you want me to
review and merge this, then pls look into atomic, since that seems
actually beneficial for my own interest". I'm not paid by intel to
review driver patches at random, but to keep overall drm in nice
shape. Moving drivers to atomic and using more shared infrastructure
is in that interest, reviewing random driver patches isn't. Sorry for
not making clear, I kinda have that as my implicit context.
