2024-04-16drm/bridge: lt9611uxc: Don't log an error when DSI host can't be foundNícolas F. R. A. Prado
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.
