Prado [ Upstream commit cd0a2c6a081ff67007323725b9ff07d9934b1ed8 ] 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.
