[PATCH] drm/tilcdc: Convert drm_atomic_helper_suspend/resume()

From: Souptick Joarder
Date: Wed Aug 08 2018 - 12:13:55 EST


convert drm_atomic_helper_suspend/resume() to use
drm_mode_config_helper_suspend/resume().

saved_state in tilcdc_drm_private will not be used
anymore, so it can be removed.
