Hi Duje,
thanks for your patch!

This looks right!

I missed this before, sorry.
This will probably not work. You need to register the spitz_led_device
first, then
you can get the gpiod:s.
The lookup will use the device name to locate the device, and if the device
isn't there it can't be found.
Yours,
