That's a pretty moot explanation. These tools will have to deal with
random changes being done to the kernel as the project keeps seeing more
changes.

Plus, you may get Paul to do what you him to do here and not put
anything in the header, but there is no guarantee someone else won't be
doing it, and even if you are CC'd on the patches, what if you are not,
and what if you can't defend this "breaks our tools" position, does not
scale to me.

If it's an internal tool, it can certainly be fixed, if it's coming from
an external vendor, I'd be seriously concerned if their scanning/logic
started to break in 4.13 because Paul's patches got included...

At any rate, I'd just drop the MODULE_AUTHOR() altogether, we can use
the SCM to tell us who did what exactly in a much more powerful way
(like line by line).
