From 9ed92dd29015de67041cf45f364a46f1fa84bf79 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Wed, 3 Feb 2016 20:11:32 +0100 Subject: [PATCH] mtd: nand: fsl_ifc: use mtd_ooblayout_xxx() helpers where appropriate The mtd_ooblayout_xxx() helper functions have been added to avoid direct accesses to the ecclayout field, and thus ease for future reworks. Use these helpers in all places where the oobfree[] and eccpos[] arrays where directly accessed.
