drm/i915: be less verbose about inability to provide vendor backlight
commit 28dcc2d60cb570d9f549c329b2f51400553412a1
Author: Jani Nikula <jani.nikula@intel.com>
Date: Mon Sep 3 16:25:12 2012 +0300
drm/i915: do not expose a dysfunctional backlight interface to userspace
prevents backlight interface creation if the BIOS has not set the backlight
PWM CTL registers that contain the max PWM value. It's apparently normal on
those machines, so demote the message about it to debug level.
