Arend Van Spriel 1b57b6210f cfg80211: make cfg80211_sched_scan_results() work from atomic context ... Drivers should be able to call cfg80211_sched_scan_results() from atomic context. However, with the introduction of multiple scheduled scan feature this requirement was not taken into account resulting in regression shown below.
