[PATCH v2 0/9] drm: Third attempt at fixing the fb-helper .best_encoder() mess

[Ville Syrjala]

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

Changes from the previous version mainly involve Danoie's suggestion
of hiding the drm_encoder_find() in the iterator macro. I also polished
the msm and tilcdc cases a bit more with another small helper.

[PATCH v2 8/9] drm/msm: Use drm_connector_has_possible_encoder()

[Ville Syrjala]

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

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

Can't type today either: "Daniel's"
