I do find the build error id:
-rw-rw-r-- 1 kbuild kbuild 272 2014-10-29 23:11 /kbuild-tests/build-error/drivers-of-base.c:warning:control-reaches-end-of-non-void-function
However there happens to be an old one half year ago. Since I never
delete old warnings, it prevents the reporting of the new warning on
your tree..
% cat /kbuild-tests/build-error/drivers-of-base.c:warning:control-reaches-end-of-non-void-function
drivers/of/base.c:1147:1: warning: control reaches end of non-void function [-Wreturn-type]

The easiest way to fix it is to delete any old error/warnings that
have been *inactive* for more than 2 months (which means they are
likely fixed).
Thanks,
