I don't want entire mtd/next. I could take Renesas hyperbus specific
commits. Another solution is me to rebase on some rcX, if that commit
was sent as fix for current cycle.
The third option is to simply resolve a conflict - which should looks
pretty easy and compile-testable. In that case the commit should be
rebased on my v5.19-rc1.

Best regards,
