This was previously enabled only when building with either
"make W=1" or "make C=1", but not the default build, which
explains why it only showed up after the merge into linux-next
that has the corresponding scripts/Makefile.extrawarn change.

It would still be a good idea to add the extra compiler (W=1)
and sparse (C=1) warnings in your CI system and address all
other issues that might uncover.
