Prado [ Upstream commit 5ff5505b9a2d827cae3f95dceba258c963138175 ] 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.
