From 74641d75275936796d239f828b80cb030e9f9b0a Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Thu, 8 Mar 2007 12:20:12 +0200 Subject: [PATCH] [MTD] Correct partition failed erase address If an erase operation fails, the address at which the failure occurred is returned by the driver. The MTD partition must adjust this address (by subtracting the partition offset) before returning to the caller. This was not happening, which caused JFFS2 to mark the wrong block bad!
