From 10d8d366790ff8da28c1853b2c795f3a74a4fdaa Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 12 Jun 2014 17:48:52 +0200 Subject: [PATCH] drm/i915: Unifiy GT powersave suspend logic Jesse's patch to only quiescent our rps work and Imre's fix to address a race with runtime pm and the forcewake reference held by the used diverging means to address the same bug: Jesse's patch uses flush_delayed_work while (since we want to make sure rps is set up) while Imre's used a cancel+manuel refcount adjustment. Unify them again by simply reusing intel_suspend_gt_powersave in intel_disable_gt_powersave.
