I see the following error at boot in a ToT samus build (with Bluetooth disabled, if that's relevant):

[2133:2133:0809/143857:WARNING:arc_bluetooth_bridge.cc(1336)] no Bluetooth instance available

Here's the code:

----

bool ArcBluetoothBridge::HasBluetoothInstance() const {
  if (!arc_bridge_service()->bluetooth()->instance()) {
    LOG(WARNING) << "no Bluetooth instance available";
    return false;
  }

  return true;
}

----

Under what circumstances does this happen? Is it always an error, or is it expected in some cases? If it's expected, I'm happy to delete the message.
