I briefly looked at directly backporting this to dev-6.6 from upstream
(8ecf60c3b3d4), but doing so generated conflicts. Did you find the
same? If so, please add a short note about what you fixed to the
trailer as well as your S-o-b tag, e.g.

Patch reports fuzz when I apply this to the tip of dev-6.6, which is
currently 5a4c98323b01 ("Merge tag 'v6.6.90' into for/openbmc/dev-
6.6"). Can you address that and re-send?

Cheers,
