Ville Syrjälä 11a85d6ab1 drm/i915: Skip vblank wait if cxsr was already off ... Before we attempt to turn any planes on or off we must first exit csxr. That's due to cxsr effectively making the plane enable bits read-only. Currently we achieve that with a vblank wait right after toggling the cxsr enable bit. We do the vblank wait even if cxsr was already off, which seems wasteful, so let's try to only do it when absolutely necessary. We could start tracking the cxsr state fully somewhere, but for now it seems easiest to just have intel_set_memory_cxsr() return the previous cxsr state.
