From 800ffd3496987e91f599a135060ef49731e045ac Mon Sep 17 00:00:00 2001 From: Artem Bityutskiy Date: Mon, 2 Jan 2012 13:59:12 +0200 Subject: [PATCH] mtd: do not use mtd->block_markbad directly Instead, use the new 'mtd_can_have_bb()', or just rely on 'mtd_block_markbad()' return code, which will be -EOPNOTSUPP if bad blocks are not supported.
