mtdchar: fix usage of mtd_ooblayout_ecc()
commit6de564939e
upstream. Section was not properly computed. The value of OOB region definition is always ECC section 0 information in the OOB area, but we want to get all the ECC bytes information, so we should call mtd_ooblayout_ecc(mtd, section++, &oobregion) until it returns -ERANGE. Fixes:c2b78452a9
