mb/lenovo/t420s: Add support for ThinkLight
With this patch, the ThinkLight on the ThinkPad T420S 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 T420S to test this.
