From mboxrd@z Thu Jan 1 00:00:00 1970 From: boris.brezillon@free-electrons.com (Boris Brezillon) Date: Thu, 4 Feb 2016 11:06:33 +0100 Subject: [PATCH v2 10/51] mtd: nand: gpmi: use mtd_ooblayout_xxx() helpers where appropriate In-Reply-To: <1454580434-32078-1-git-send-email-boris.brezillon@free-electrons.com> References: <1454580434-32078-1-git-send-email-boris.brezillon@free-electrons.com> Message-ID: <1454580434-32078-11-git-send-email-boris.brezillon@free-electrons.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
