drm/vc4: hdmi: Don't access the connector state in reset if kmalloc fails
drm_atomic_helper_connector_reset uses kmalloc which, from an API standpoint, can fail, and thus setting connector->state to NULL. However, our reset hook then calls drm_atomic_helper_connector_tv_reset that will access connector->state without checking if it's a valid pointer or not. Make sure we don't end up accessing a NULL pointer. Acked-by:Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by:
