I build with CONFIG_WERROR=y, which turns all warnings
into errors. It's just a warning without that, and is
currently only enabled when building with 'make W=1',
though the point of my series is to have it always enabled.

It's clearly harmless and could be backported, but it
is not needed either since older kernels will keep the
option as part of W=1, not the default.
