Did a quick search. Turns out this is mainline commit 6bee098b914176
("drm: Fix use-after-free on framebuffers and property blobs when
calling drm_dev_unplug") -- and when searching for that (FWIW, this is
not widely known, but that is really helpful in case like this, as the
mainline commit id is way more relevant) is turns out that is in the
process of getting reverted:
See https://lore.kernel.org/all/20260326082217.39941-2-dev@lankhorst.se/
or 45ebe43ea00d6b ("Revert "drm: Fix use-after-free on framebuffers and
property blobs when calling drm_dev_unplug"") [next-20260327
(pending-fixes)].
Sasha and Greg: you might want to make sure to pick this up.
Ciao, Thorsten
