carl9170: Only specify interface combinations if more than one interface is possible
Otherwise carl9170 triggers a warning in cfg80211, from net/wireless/core.c /* Combinations with just one interface aren't real */ if (WARN_ON(c->max_interfaces < 2)) Note: The number of supported interfaces is set by the carl9170 firmware. The default number of supported interfaces for all current firmwares is 2. Therefore this warning can only be observed with custom firmwares.
