Backlights controlled by i915.ko and only associated with its connectors
and also only associated with the intel_drmfb fbcon, controlled by
i915.ko. In this situation, we already handle adjusting the backlight
when the fbcon is blanked/unblanked and do not require backlight trying
to do the same.
Attempting to register with the fbdev as a client causes lockdep to warn
about a dependency cycle:
