Well the fix is trivial, but somehow rebuilding drm-tip always fails for me while merging drm-intel-next.

I probably have somehow messed up reverting the conflict resolution. Ideas?

It looks like the error is in the wrong conflict resolution in
629041de3a0c M─┐ Merge remote-tracking branch 'drm-misc/drm-misc-next' into drm-tip
you'd need to redo the merge (-i) after telling git
rerere to forget the previous conflict resolution.

https://drm.pages.freedesktop.org/maintainer-tools/drm-tip.html#removing-a-wrong-conflict-resolution

it's also useful to use dim -i, to make sure we can build on each merge
afterwards.

AFAICS the revert would be on 141577c6d0bd ("2022y-03m-29d-09h-01m-04s UTC: drm-tip rerere cache update")

taking a stab on it, should be like below. It even builds,
but I have no confidence to commit it.
