[Intel-gfx] [PATCH] drm/i915: resume MST after reading back hw state

2014-12-07 Thread Dave Airlie
From: Dave Airlie Otherwise the MST resume paths can hit DPMS paths which hit state checker paths, which hit WARN_ON, because the state checker is inconsistent with the hw. This fixes a bunch of WARN_ON's on resume after undocking. Signed-off-by: Dave Airlie --- drivers/gpu/drm/i915/i915_drv.
