		ret = mtd_device_unregister(nand_to_mtd(&anand->chip));
		WARN_ON(ret);
		nand_cleanup(&anand->chip);

Or maybe add this WARN_ON() to nand_release() so we don't have to ask
people to use mtd_device_unregister() + nand_cleanup(). We really
should fix that at some point (allocate nand_chip and mtd_info
separately and leave a dummy mtd_info object with all hooks returning
ENODEV when the unregister fails).
