In fact, this patch creates an unmet dependency problem, we also need to
select MTD and MTD_NAND otherwise we run into a linking error while
building the brcmnand driver:

  LD      init/built-in.o
drivers/built-in.o: In function `brcmnand_remove':
/home/fainelli/dev/linux/drivers/mtd/nand/brcmnand/brcmnand.c:2234:
undefined reference to `nand_release'

/home/fainelli/dev/linux/drivers/mtd/nand/brcmnand/brcmnand.c:1933:

/home/fainelli/dev/linux/drivers/mtd/nand/brcmnand/brcmnand.c:1958:
undefined reference to `nand_scan_tail'
Makefile:931: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

I will take care of that and send a fix for 4.2.
