From fc002e3c320602d0e206f607aca0460540d7637a Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Wed, 28 Dec 2011 18:35:07 +0200 Subject: mtd: introduce mtd_has_oob helper We are working in the direction of making sure that MTD clients to not use 'mtd->func' pointers directly. In some places we want to know if OOB operations are supported by an MTD device. Introduce 'mtd_has_oob()' helper for these purposes.
