[Intel-gfx] [PATCH] [CFT] drm/i915: Only set the down rps limit when at the loweset frequency

[Chris Wilson]

And then I remembered I was going to mention...

I spent yesterday evening trying to tempt the fail back to IVB, to no
avail. So I think the underlying cause was the sporadic read returning 0
which we promptly set to rplim with the original rmw sequence. Then we
falsely continued to warn during intel_sanitize_pm() due to the same
sporadic read failure. So I think we have painted all the elephants
here.
