[Intel-gfx] [PATCH v2 5/9] drm/nouveau: Use drm_connector_for_each_possible_encoder()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Use drm_connector_for_each_possible_encoder() for iterating
connector->encoder_ids[]. A bit more convenient not having
to deal with the implementation details.

v2: Replace drm_for_each_connector_encoder_ids() with
    drm_connector_for_each_possible_encoder() (Daniel)
