This series should shut up all warnings introduced by gcc-6 or gcc-7 on today's linux-next, as observed in "allmodconfig" builds on x86, 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.
