Small update: I noticed that having ccache being the default compiler
even with CCACHE_DISABLE=1 causes a lot of these warnings. Completely
taking ccache out of the picture however seems to have eliminated the
warnings about v4l2_subdev_call() and other silly warnings, but not
the interesting ones in the -Wint-in-bool-context category.
