Hello.

Actually, build fails only for starfive target that uses non-mainline
custom linux repo not haveing a branch with linux >= 6.7.

I think, the patch is worth applying at least for linux-starfive_6.6-
visionfive2.bb.

Other targets are using bookworm at most, so for could leave them as is
for now.

What do you think?
