For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From da0ec3df4b9ff45e8e653ff534721275c1dfecab Mon Sep 17 00:00:00 2001 From: Larry Finger <Larry.Finger@lwfinger.net> Date: Wed, 6 Feb 2013 12:54:17 -0600 Subject: [PATCH] rtlwifi: rtl8192cu: Fix NULL dereference BUG when using new_id commit 957f4aca5fa0db69635271bc4621cc0b65b2d590 upstream. When the new_id entry in /sysfs is used for a foreign USB device, rtlwifi BUGS with a NULL pointer dereference because the per-driver configuration data is not available.
