* git://git.infradead.org/mtd-2.6:
[MTD] [NAND] drivers/mtd/nand/nandsim.c: fix printk warnings
[MTD] [NAND] Blackfin NFC Driver: Cleanup the error exit path of bf5xx_nand_probe function
[MTD] [NAND] Blackfin NFC Driver: use standard dev_err() rather than printk()
[MTD] [NAND] Blackfin NFC Driver: enable Blackfin nand HWECC support by default
[MTD] [NAND] Blackfin NFC Driver: add proper devinit/devexit markings to probe/remove functions
