I was okay even with the previous solution to modify
GENMASK_INPUT_CHECK() and this one is fine to me as well.
The presense of warnings on W=1 doesn't mean we shouldn't fix W=12
etc. Especially when their rootfs are in headers and blow up the
output. Especially when it's 1/3 of all warnings.
`make W=12[e] path/to/new/file` is still useful to ensure that we
don't add more warnings to the already existing ones. When there are
problematic header, it's easier to miss something and impossible to
pipe `make W=12e` in a script to do that in an automated manner.
Thanks!
