From 3b26b1100e26811e54770abaa221eae140ba840d Mon Sep 17 00:00:00 2001 From: Zhu Yi <yi.zhu@intel.com> Date: Thu, 17 Nov 2005 13:58:30 +0800 Subject: [PATCH] [PATCH] ipw2200: fix error log offset calculation This fixes a slab corruption issue in the ipw2200 driver: it essentially multiplied the error log number _twice_ by the size of the error element entry (once explicitly in the code, and once implicitly as part of the regular pointer arithmetic).
