The probe() function for GATT profiles should be transport agnostic. There is a btd_device_get_primaries() method which can be used to return a list of discovered GATT Primary Services, and it works for BR/EDR and LE. It is already used for Proximity, for instance. device_services_from_record() is BR/EDR specific and should not be used by GATT profile code. It also fixes a memory leak, given device_services_from_record() returns a heap allocated GSList.
