From: Aditya Kumar Singh Date: Fri, 6 Sep 2024 12:14:20 +0530 Subject: [PATCH] wifi: mac80211: remove label usage in ieee80211_start_radar_detection() After locks rework [1], ieee80211_start_radar_detection() function is no longer acquiring any lock as such explicitly. Hence, it is not unlocking anything as well. However, label "out_unlock" is still used which creates confusion. Also, now there is no need of goto label as such. Get rid of the goto logic and use direct return statements.
