No, there is no need to convert the kernel to the "latest" spdx level,
when we started out there was no "-only" nonsense (hint no other license
has that crud), and "GPL-2.0" is a totally valid summary of the license.

So please don't go changing it all in-kernel, that way lies madness.
Let's finish fixing up ALL kernel files before worrying about what SPDX
"version" we are at.

thanks,
