At the moment this driver fails to load if no encoders/connectors were found. In case other drivers that register encoders/connectors (tilcdc_panel) are defered it would be better to check for encoders/connectors later again. This patch replaces the returncode -ENXIO with -EPROBE_DEFER to get a working setup even if tilcdc_panel probes after tilcdc.
