[PATCH v3 09/19] drm/i915: clean up atomic plane check functions, v2.

Maarten Lankhorst
2015-06-15T10:34:14Z

By passing crtc_state to the check_plane functions a lot of duplicated
code can be removed. There are still some transitional helper calls,
they will be removed later.

Changes since v1:
- Revert state->visible changes.
- Use plane->state->crtc instead of plane->crtc.
- Use drm_atomic_get_existing_crtc_state.
