Prado [ Upstream commit 272377aa0e3dddeec3f568c8bb9d12c7a79d8ef5 ] 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.
