[Intel-gfx] [PATCH 1/2] drm/i915: Identify Cometlake platform
Chris Wilson
chris at chris-wilson.co.uk
Tue Jun 2 12:15:56 UTC 2020
Cometlake is small refresh of Coffeelake, but since we have found out a
difference in the plaforms, we need to identify the separate platforms.
Since we previously took Coffeelake/Cometlake as identical, update all
IS_COFFEELAKE() to also include IS_COMETLAKE().
