Increase in system time is somewhat expected, since we'll do more
bit banging now. Any chance of comparison against bffce907d640^
aka. 0aeb904888f5 ("drm/i915: simplify gmbus xfer error checks") ?
I would hope that the result would be more or less the same as with
0bbca274a31c ("drm/i915: Actually retry with bit-banging after GMBUS timeout")
