From 33c8df89351709ea79f2d384179b76df475b43ff Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Wed, 10 Feb 2016 13:49:37 +0100 Subject: [PATCH] drm/i915: Unify power domain handling. Right now there's separate power domain handling for update_pipe and modesets. Unify this and only grab POWER_DOMAIN_MODESET once.
