NAND_ECC_INVALID = -1, NAND_ECC_NONE = 0, Unless you plan to add an entry for ECC_INVALID in nand_ecc_modes, of course, in which case you indeed want to start at 0. Regardless of that, the change looks good to me: Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> > NAND_ECC_NONE, > NAND_ECC_SOFT, > NAND_ECC_HW,

NAND ECC modes (or providers) have their own enumeration but, unlike their algorithms counterpart, there is no invalid or uninitialized value to discriminate between an error and having chosen a no-ECC situation. Add an "invalid" entry for this purpose.
