Prado [ Upstream commit ef4a9204d594fe959cdbc7418273caf4001535c8 ] 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.
