In 'hci_conn_del_sysfs()', 'device_unregister()' may be called when an underlying (kobject) reference counter is greater than 1. This means that reparenting (happened when the device is actually freed) is delayed and, during that delay, parent controller device (hciX) may be deleted. Since the latter may create a dangling pointer to freed parent, avoid that scenario by reparenting to NULL explicitly.
