From: Gustavo Padovan <[email protected]> Fixes an regression added by 3ae2436 (drm/exynos/mixer: replace direct cross-driver call with drm mode) and while this regression was caused by a change in the exynos driver it makes sense to add the check on atomic core to benefit other drivers as well.
The whole atomic update fails if the exynos hdmi display is not present/active. Add a test to only run atomic_check() if the CRTC is active.
