From 431e1ecabddcd7cbba237182ddf431771f98bb4c Mon Sep 17 00:00:00 2001 From: Felix Radensky Date: Mon, 25 Apr 2011 01:57:12 +0300 Subject: [PATCH] mtd: mtdconcat: fix NAND OOB write Currently mtdconcat is broken for NAND. An attemtpt to create JFFS2 filesystem on concatenation of several NAND devices fails with OOB write errors. This patch fixes that problem.
