[PATCH v2 4/9] drm/bridge: lt9611: Don't log an error when DSI host can't be found

From: Nícolas F. R. A. Prado
Date: Thu Feb 29 2024 - 19:13:23 EST


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.
