mtdchar: fix usage of mtd_ooblayout_ecc()
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: c2b78452a9db ("mtd: use mtd_ooblayout_xxx() helpers where appropriate") Cc: <stable@vger.kernel.org> Signed-off-by: OuYang ZhiZhong <ouyzz@yealink.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
