That build warning actually happens with clang, not GCC as far as I am
aware, and it is actually a hard build error with older versions of
clang, as Arnd points out in his patch to fix this (although the warning
is a hard error with CONFIG_WERROR too, which causes allmodconfig to
break):

Samuel's patch was even simpler:

Why was one of these changes not applied before this was sent? I am
aware you were on vacation recently but you are now adding a known issue
to -rc1, which can proliferate to other maintainer's trees and makes
testing for us more difficult :/ -next has been broken for the entire
merge window over this, which is usually when there is a chance we can
get maybe a week of green builds...

Cheers,
Nathan
