Kernel code doesn't use a signed char or short with %hx or %hu very often
but in case you didn't already know, any signed char/short emitted with
anything like %hx or %hu needs to be left alone as sign extension occurs so:

Yes, this would also effect checkpatch.

Of course but checkpatch is stupid and doesn't know types
so it just assumes that the type argument is not signed.

In general, that's a reasonable but imperfect assumption.

coccinelle could probably do this properly as it's a much
better parser.  clang-tidy should be able to as well.
