The patch titled
Support enable/disable of WAN module in ibm_acpi
has been removed from the -mm tree. Its filename is
support-enable-disable-of-wan-module-in-ibm_acpi.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.

Subject: Support enable/disable of WAN module in ibm_acpi
From: Jeremy Fitzhardinge <jeremy@xxxxxxxx>
The WAN (Sierra Wireless EV-DO) module is very similar to the Bluetooth
module. It appears on the USB bus when enabled. It can be controlled via
hot key, or directly via ACPI. This change enables direct control via
ACPI.
I have tested it on my Lenovo Thinkpad X60; I guess it will probably work
on other Thinkpad models which come with this module installed.
