Recently moved from REDHAT 7 to Fedora 26 and keyboard leds stopped working.
I had RHEL 7 because my VAIO have an ATI Radeon GPU and AMD support is only for RHEL.
However I grew tired of having old development libraries so I am now using Fedora 26.

The thing is my keyboard lights worked fine in RHEL 7 and not at all in Fedora 26.
Here you can see "kbd_backlight" is not listed as a platform device:

To be honest, I've no answer :P

While there might be some workaround, please fill a bug against Fedora 26, so that it'll be properly fixed (hopefully) :)
