Yes, you should. I just built 6.4 allmodconfig and there are no warnings
anymore likely because clang enables this warning by default and since we build
the kernel with both compilers, people have fixed them all in the meantime.

And clang did catch a legitimate error with this warning here while gcc didn't
using the default warning flags but it warned with -Wextra.

So I think we'll enable that warning by default in the kernel build and it does
make sense to do that in gcc too, I'd say.

Thx.
