This code is just weird. If CONFIG_OF is not enabled, then board.c
shouldn't be compiled at all. You can do this with a patch to the
Kconfig and Makefile. Also, if the functions in
drivers/staging/board/board.c are needed for driver support, then please
propose a patch that moves them in into drivers/of/base.c so that they
can be reviewed properly. They are so short and simple that fixing them
up as part of the normal review process should be sufficient.
As for fixing the compile error, please drop the change to
include/linux/of.h and resubmit.
