Hi Mario,
Yes, this problem is on amd-staging-drm-next and I checked the adeucher/amd-staging-drm-next, this patch is not in there.
Best Regards,

This is a backport from 6.6-rc1, I suppose you're sending the backport out because missing it is causing problems testing either amd-staging-drm-next or drm-next, right?
If the problems are amd-staging-drm-next I think you can:
# git cherry-pick -x 90ca51e8c654699b672ba61aeaa418dfb3252e5e
and commit there. Alex will just skip it when he builds the next PR or rebases to a newer release.
If the problem is on drm-next, we'll need to wait for drm-next to move up rather than cherry-picking it there.
