From 4a43faf54e9173b6acce37cf7f053fc9515a2cdf Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Fri, 25 May 2012 16:22:42 +0200 Subject: [PATCH] mtd: mxc_nand: move ecc strengh setup before nand_scan_tail Since commit 6a918bade9dab40aaef80559bd1169c69e8d69cb, the mxc_nand driver fails with: Driver must set ecc.strength when using hardware ECC This is because nand_scan_tail checks for correct ecc strength settings, so we must set them up before nand_scan_tail.
