Jesse Barnes 390c4dd448 drm/i915: handle FIFO oversubsription correctly ... If you're pushing a plane hard (i.e. you need most or all of the FIFO entries just to cover your frame refresh latency), the watermark level may end up being negative. So fix up the signed vs. unsigned math in the calculation function to handle this correctly, giving all available FIFO entries to such a configuration.
