Yes, this got delayed and didn't get to -rc1, maybe I could've merged
the fixes already reviewed earlier.

The fix is in drm-misc-next-fixes atm and Thomas has sent already

https://lore.kernel.org/all/20250812064712.GA14554@2a02-2454-fd5e-fd00-2c49-c639-c55f-a125.dyn6.pyur.net

which should get pulled to drm-fixes and then to -rc2, AFAIU, not sure
if that's enough for you. I let the maintainers comment about
cherry-picking it if not, I suppose the concern could be the duplicated
commits that Linus would see.
