This function in use (incorrectly) by
drivers/net/ethernet/oki-semi/pch_gbe/pch_gbe_main.c
Your patch will break it.
I didn't check other functions, but assume they are broken too.
Thanks

Seems like the more appropriate fix is to include the right header so
that these functions do have prototypes.
