mb/lenovo/x200: Add support for ThinkLight
With this patch, the ThinkLight on the ThinkPad X200 can be controlled through the OS. This was initially done for the X201 in f63fbdb6: mb/lenovo/x201: 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 I have tested it on an X200 with Kernel 5.4 and it seems to work fine.
