mb/lenovo/t400: Add support for ThinkLight
With this patch, the ThinkLight on the ThinkPad T400 can be controlled
through the OS. The same change was done for the ThinkPad X200 in
b45912f4: mb/lenovo/x200: Add support for ThinkLight
After applying this patch, the light can be controlled like this:
echo on >/proc/acpi/ibm/light
echo off >/proc/acpi/ibm/light
Or through sysfs at /sys/class/leds/tpacpi::thinklight
Unfortunately I do not own a T400 to test this.
