Choose between atomic or non atomic connector dpms helper. If tda998x is connected to a drm driver that does not support atomic modeset calling drm_atomic_helper_connector_dpms() causes a crash when the connectors atomic state is not initialized. The patch implements a driver specific connector dpms helper that calls drm_atomic_helper_connector_dpms() if driver supports DRIVER_ATOMIC and otherwise it calls the legacy drm_helper_connector_dpms(). Fixes commit 9736e988 ("drm/i2c: tda998x: Add support for atomic modesetting"). Signed-off-by:
