At least the most popular drivers should be okay. If anyone will find issue introduced by this series, then indeed shouldn't be a problem to fix it later on. > Do you have commit rights to drm-misc-next or should I push it? I got the drm-misc commit right two weeks ago, haven't pushed anything there yet. Please let me try to do the push. I'll let you know if any kind of help will be needed from you. I'll wait for more acks/r-bs and then do the push. -- Best regards, Dmitry
