From 211bf20c35838b2181e8d04fd7ce8a7ac6e68db1 Mon Sep 17 00:00:00 2001 From: Mike Dunn Date: Mon, 17 Jun 2013 10:44:55 -0700 Subject: [PATCH] mtd: nand/docg4: fix driver after Linux resync Commit dfe64e2c89731a3f9950d7acd8681b68df2bae03: mtd: resync with Linux-3.7.1 broke the docg4 driver. Specifically: - some of the prototypes of the ecc methods changed - the NAND_NO_AUTOINCR flag was removed - the ecc.strength element was added. This patch fixes these. Tested on the docg4 on my palmtre680 board.
