Prado [ Upstream commit b3b4695ff47c4964d4ccb930890c9ffd8e455e20 ] 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.
