From 3538c56329936c78f7d356889908790006d0124c Mon Sep 17 00:00:00 2001 From: Roman Tereshonkov Date: Fri, 2 Dec 2011 15:07:17 +0200 Subject: mtd: mtdoops: skip reading initially bad blocks Use block_isbad to check and skip the bad blocks reading. This will allow to get rid of the read errors if bad blocks are present initially.
