[PATCH] Note inspiration for this script to give credit where it's due

[Bradley M. Kuhn]

To give some extra context on this patch that I sent earlier today:

I work for Software Freedom Conservancy (SFC) as our Policy Fellow.
OpenWrt is, as many of you know, a member project of SFC.

Some of the leaders of OpenWrt asked me and my colleagues to review this
situation regarding the file `scripts/kernel_bump.sh`.  As you can see in my
commit message:

> [T]he commit message on 7b7f1702 incorrectly indicates that there was
> "potential fear" about copyright infringement.

> Upon review of this situation, there is, in my opinion, no concern of
> copyright infringement here.  This is not legal advice; it is my opinion
> based of years of work on copyright policy for FOSS.

> However, Elliott Mitchell's idea was obviously helpful as inspiration in
> writing this script and deserves credit.  Ideas alone, however, are not to
> our knowledge copyrightable anywhere in the world.

IOW, our conclusion is that the situation is fully resolved, but we
nevertheless recommend that a thank-you to Elliott for the idea (in the file
itself) is appropriate.

Thanks for your consideration of my patch to resolve this matter.  I would
welcome `Signed-Off-By`s from others who were involved with work related to
`scripts/kernel_bump.sh` if you're willing.

Thanks!
