Subject: [PATCH] ARM: OMAP2+: Fix GPMC errors when CONFIG_MTD_NAND_OMAP2 is
 a module
Message-ID: <20120229173159.GM18901@atomide.com>
To: linux-arm-kernel@lists.infradead.org
List-Id: linux-arm-kernel.lists.infradead.org

Otherwise we can get:

ERROR: "gpmc_calculate_ecc" [drivers/mtd/nand/omap2.ko] undefined!
ERROR: "gpmc_enable_hwecc" [drivers/mtd/nand/omap2.ko] undefined!
