Subject: drm/i915: hook up LVDS DPMS property
X-Git-Tag: firefly_0821_release~15768^2~3
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=335041ed31d774391d9add49824d05e7d19d93e9;p=firefly-linux-kernel-4.4.55.git

drm/i915: hook up LVDS DPMS property

The LVDS output supports DPMS calls, but we never hooked up the property code,
so set property calls didn't actually do anything.  Implement a set_property
callback for the LVDS output so that the right thing happens.
