Subject: drm/tilcdc: Use drm_connector_has_possible_encoder()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0b7510d15e14ba628ab9bacd6516e3f6a35ba21f;p=openwrt%2Fstaging%2Fblogic.git

drm/tilcdc: Use drm_connector_has_possible_encoder()

Use drm_connector_has_possible_encoder() for checking
whether the encoder has an associated connector.

v2: Replace the drm_for_each_connector_encoder_ids() loop
    with a simple drm_connector_has_possible_encoder() call
