    drm/bridge: tc358775: Don't log an error when DSI host can't be found
    
    [ 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.
