I didn't add it, it was already there.  I just made it uniform with the
others.  Maybe the hand-editted duplication had left it not working?  Or
not entirely removed when it was intended to be?

Yeah, it forms a sed s command.

That matters when doing the variant-source packages like kernel-vanilla,
which I haven't tested lately.  For the "install the kernel-foo package"
parts of %description, %{name}-foo might be better since it will make the
literal instructions match the intended reality for that case.

For the provides/requires some are intended to be %{name} and some kernel.
i.e., %{name}-debuginfo-common-%{_target_cpu}, but kernel-drm.
