From 327cf2922b4edf0439b219469722d2a502e37349 Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Fri, 30 Dec 2011 16:35:35 +0200 Subject: mtd: do not use mtd->sync directly This patch teaches 'mtd_sync()' to do nothing when the MTD driver does not have the '->sync()' method, which allows us to remove all direct 'mtd->sync' accesses.
