[PATCH] checkpatch.pl: adapt to new Assisted-by: format

[PATCH] checkpatch.pl: adapt to new Assisted-by: format

[Jeff Layton]

There is a new format for the 'Assisted-by:' tag. Change checkpatch.pl
to just check that it has a value rather than testing for a specific
format.

Assisted-by: LLM
Signed-off-by: Jeff Layton <jlayton@kernel.org>
---
This is a companion patch to the one to change the format in
Documentation/. See:

Did an LLM really help produce this?  Why?

Why not? It was simple to have it do it, and my perl skills are a bit
rusty. I don't love typing, fwiw...

Applied... we don't have a Sure-whatever-by tag, so I didn't add
Joe's...

Thanks,
