Subject: [PATCH] bcm47xx: fix build regression

An unknown change in the kernel headers caused a build regression
in an MTD partition driver:

In file included from drivers/mtd/bcm47xxpart.c:12:0:
include/linux/bcm47xx_nvram.h: In function 'bcm47xx_nvram_init_from_mem':
include/linux/bcm47xx_nvram.h:27:10: error: 'ENOTSUPP' undeclared (first use in this function)

Clearly we want to include linux/errno.h here.
