I think you also need this one:

Subject: [PATCH] mtd: brcmnand depends on MTD_NAND

MTD_NAND_BRCMNAND uses the generic nand functions, but is currently allowed
to be built without CONFIG_MTD_NAND, which results in a link error:

drivers/built-in.o: In function `brcmnand_remove':
coresight-replicator.c:(.text+0x17ae6c): undefined reference to `nand_release'
drivers/built-in.o: In function `brcmnand_probe':
coresight-replicator.c:(.text+0x17d4b4): undefined reference to `nand_scan_ident'
coresight-replicator.c:(.text+0x17d948): undefined reference to `nand_scan_tail'

This adds an explicit Kconfig dependency.
