Since add more warnings for inconsistent ops in cfg80211, the wireless core warns if a driver implements a cfg80211 callback but doesn't implements the inverse operation. The ath6kl driver implements a cfg80211 .get_antenna operation handler but doesn't have the inverse .set_antenna callback. So, it makes warning. To remove this warning, add .set_antenna callback in ath6kl driver and also send a cmd to firmware with it's values.
