mtd: nand: return consistent error codes in ecc.correct() implementations
The error code returned by the ecc.correct() are not consistent over the all implementations. Document the expected behavior in include/linux/mtd/nand.h and fix offending implementations. [Brian: this looks like a bugfix for the ECC reporting in the bf5xx_nand driver, but we haven't seen any testing results for it] Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Tested-by: Franklin S Cooper Jr. <fcooper@ti.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
