From: Ville Syrjälä <[email protected]> Currently we only set the DRM_CONNECTOR_POLL_{DISCONNECT,CONNECT} bits in intel_connector->polled (the base setting), leading to some confusing looking code to reset drm_connector->polled (the actual setting) to DRM_CONNECTOR_POLL_HPD. Let's set intel_connector->polled = DRM_CONNECTOR_POLL_HPD for all hpd capable connectors, and then we don't need so many special cases in the hotplug code.
