Subject: [PATCH v2 47/51] mtd: nand: vf610: switch to mtd_ooblayout_ops
Date: Thu, 4 Feb 2016 11:07:10 +0100 [thread overview]
Message-ID: <1454580434-32078-48-git-send-email-boris.brezillon@free-electrons.com> (raw)
In-Reply-To: <1454580434-32078-1-git-send-email-boris.brezillon@free-electrons.com>
Implementing the mtd_ooblayout_ops interface is the new way of exposing
ECC/OOB layout to MTD users.
