mtd_read_oob() has some unexpected similarities to mtd_read(). For instance, when ops->datbuf != NULL, nand_base.c might return max_bitflips; however, when ops->datbuf == NULL, nand_base's code potentially could return -EUCLEAN (no in-tree drivers do this yet). In any case where the driver might return max_bitflips, we should translate this into an appropriate return code using the bitflip_threshold. Essentially, mtd_read_oob() duplicates the logic from mtd_read(). This prevents users of mtd_read_oob() from receiving a positive return value (i.e., from max_bitflips) and interpreting it as an unknown error. Artem: amend comments.
