From 5f9994bd4a58f72a4312fb3e09c7fe2c4ca95b82 Mon Sep 17 00:00:00 2001 From: Michael Braun Date: Mon, 10 Oct 2016 19:12:20 +0200 Subject: mac80211: remove unnecessary num_mcast_sta check Checking for num_mcast_sta in __ieee80211_request_smps_ap() is unnecessary as sta list will be empty in this case anyway, so the list iteration will just exit immediately. Since this isn't a "hot" code path, it doesn't really matter, and the next patch will redefine num_mcast_sta to make this check invalid.
