If you don't expect an sdr-base as part of the normal operations of that
bridge, don't bring a message that makes me think something is wrong :-)

Just changing the severity isn't enough. you should just remove the
message and later on, print/warn/error out if you decide you actually
need an sdr-base (such as in the backend).

Cheers,
Ben.
