Prado [ Upstream commit 6d9e877cde7e9b516a9a99751b8222c87557436d ] Given that failing to find a DSI host causes the driver to defer probe, make use of dev_err_probe() to log the reason. This makes the defer probe reason available and avoids alerting userspace about something that is not necessarily an error.
