drivers/staging/board/board.c already includes <linux/of.h>, which provides
the prototype, but only if CONFIG_OF=y.

However, STAGING_BOARD depends on OF_ADDRESS and OF_IRQ,
which both depend on OF. So how can this happen??

when I'm talking to journalists I just say "programmer" or something like that.
