[Intel-gfx] [PATCH v2.1 2.5/12] drm/i915: Validate the state after an atomic modeset, only, and pass the state.

[Maarten Lankhorst]

First step in removing dpms and validating atomic state.

There can still be a mismatch in the connector state because the dpms
callbacks are still used, but this can not happen immediately after a modeset.
