drm/i915: Allocate connector state together with the connectors
Connector states were being allocated in intel_setup_outputs() in loop over all connectors. That meant hot-added connectors would have a NULL state. Since the change to use a struct drm_atomic_state for the legacy modeset, connector states are necessary for the i915 driver to function properly, so that would lead to oopses. v2: Fix test for intel_connector_init() success in lvds and sdvo (PRTS) Signed-off-by: Ander Conselvan de Oliveira <ander.conselvan.de.oliveira@intel.com> Reported-and-tested-by: Nicolas Kalkhof <nkalkhof@web.de> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
