Helllo,
I just tested the above patch on my Thinkpad X1 extreme Gen 2. on manjaro with
the kernel 5.3.10 (the specs of my computer in my previous post)
And It seems to works fine on my system
Now the max brightness reported in
/sys/devices/pci0000:00/0000:00:02.0/drm/card0/card0-eDP-1/intel_backlight/max_brightness
is 2047 and the brightness control works as inteded on my plasma desktop and my
4k OLED display.
if you need more informations let me now.
