Commit7d902c05b4("drm: Nuke drm_atomic_helper_connector_dpms") removed drm_atomic_helper_connector_dpms() helper saying that it was a dead code. It was however indirectly used by Exynos DRM driver for implementing suspend/resume support. To fix this regression (after that patch Exynos DRM suspend/resume functions became no-ops and hardware fails to suspend), this patch rewrites them with drm_atomic_helper_suspend/resume() helpers.
