Turns out this one requires another commit to go with it, both for v6.7-rc* and stable backports. I was just a bit too late with it for v6.7-rc4 [1]. Please hold off with all stable backports of this until you can backport 96d7e7940136 ("drm/i915: Check pipe active state in {planes,vrr}_{enabling,disabling}()") from drm-intel-fixes with it. It should find its way to v6.7-rc5. Thanks, and sorry for the mess. :( BR, Jani.
