From 74c5b597e9c2fc728c61582afdea4971a5c8ed8f Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Mon, 30 Jul 2007 11:26:38 -0700 Subject: [PATCH] modules: better error messages when modules fail to load due to a sysfs problem. This helps people when debugging problems like the ones that were in the recent -mm releases.
