Johan Hovold e5ae01fd46 Bluetooth: fix debugfs registration ... commit fe2ccc6c29d53e14d3c8b3ddf8ad965a92e074ee upstream. Since commit ec6cef9cd9 ("Bluetooth: Fix SMP channel registration for unconfigured controllers") the debugfs interface for unconfigured controllers will be created when the controller is configured. There is however currently nothing preventing a controller from being configured multiple time (e.g. setting the device address using btmgmt) which results in failed attempts to register the already registered debugfs entries: debugfs: File 'features' in directory 'hci0' already present! debugfs: File 'manufacturer' in directory 'hci0' already present! debugfs: File 'hci_version' in directory 'hci0' already present! ... debugfs: File 'quirk_simultaneous_discovery' in directory 'hci0' already present! Add a controller flag to avoid trying to register the debugfs interface more than once.
