From 78ab67da1002d954ea4c3e2b441e2483c41f94e8 Mon Sep 17 00:00:00 2001 From: "Knobloch, Thomas" Date: Fri, 27 Apr 2007 13:19:36 +0200 Subject: [PATCH] [MTD] [NAND] Wrong calculation of page number in nand_block_bad() In case that there is no memory based bad block table available the function nand_block_checkbad() in drivers/mtd/nand/nand_base.c will call nand_block_bad() directly. When parameter 'getchip' is set to zero, nand_block_bad() will not right shift the offset to calculate the correct page number.
