This series should shut up all warnings introduced by gcc-6 or gcc-7 on

arm and arm64.

I have sent some of these before, but some others are new, as I had
at some point disabled the -Wint-in-bool-context warning in my
randconfig testing and did not notice the other warnings.

I have another series to address all -Wformat-overflow warnings,
and one more patch to turn off the -Wformat-truncation warnings
unless we build with "make W=1". I'll send that separately.

Most of these are consist of trivial refactoring of the code to
shut up false-positive warnings, the one exception being
"staging:iio:resolver:ad2s1210 fix negative IIO_ANGL_VEL read",
which fixes a regression against linux-3.1 that has gone
unnoticed since then. Still, review from subsystem maintainers
would be appreciated.

I would suggest that Andrew Morton can pick these up into linux-mm
so we can make sure they all make it into the release. Alternatively
Linus might feel like picking them all up himself.

While I did not mark the harmless ones for stable backports,
Greg may also want to pick them up once they go upstream, to
help build-test the stable kernels with gcc-7.
Thanks for these, I'll keep an eye out for them to get into the stable
trees, so I can eventually update my test-build box to gcc-7.

thanks,
