From: Adam Ford aford173@gmail.com

commit efb94790852ae673b18efde1b171d284689ff333 upstream.

The LogicPD Type28 display used by several Logic PD products has not worked since v5.6.

The connector type for the LogicPD Type 28 display is missing and drm_panel_bridge_add() requires connector type to be set.
