[Intel-gfx] [PATCH] drm/i915: Disable GT powersaving upon suspend

[Chris Wilson]

In the refactoring to stop the rpm refleak, the call to
intel_disable_gt_powersave() was mistakenly dropped from
i915_drm_suspend(). It is still required in order to set the rps.enabled
flag back to false so that it will re-enabled upon resume.
