[PATCH v4 1/4] mac80211: remove unnecessary num_mcast_sta user

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Checking for num_mcast_sta in __ieee80211_request_smps_ap() is unnecessary,
as sta list will be empty in this case anyway, so list_for_each_entry(sta,
...) will exit immediately.
