From 3ec9d6eb09ca799f2632a58012ef9603982a642d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Thu, 11 Apr 2013 09:35:41 +0000 Subject: nand: mxc: Use appropriate page number in syndrome functions MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The syndrome functions should use the page number passed as argument instead of the page number saved upon NAND_CMD_READ0. This does not make any difference if the NAND_NO_AUTOINCR option is set, but otherwise this fixes accesses to the wrong pages.
