Or > we are fragmenting backlights into different classes? The idea is to make DRM property changes propagate into a linked backlight. Applied to input-LEDs, it would mean setting LED_XYZ via input would cause an kernel-internal call into the linked led_class set_brightness(). This allows us to register an led-class per LED as you request, but at the same time allow easy access via input devices where it makes sense.
