    drm/bridge: lt8912b: Don't log an error when DSI host can't be found
    
    [ 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.
