drm-misc branches cannot be rebased, it must be reverted, but it can still be applied
on drm-misc-next and I'll send a revert patch for drm-misc-fixes if needed, not a big deal.

If you want it to be in v6.9, it's too late since the last drm-misc-next PR has been sent
yesterday (https://cgit.freedesktop.org/drm/drm-misc/tag/?h=drm-misc-next-2024-02-22)

Please ping Thomas or Maxime, perhaps it's not too late since the drm-misc-next tree
really closes on sunday.
