Subject: cfg80211: add cfg80211_sched_scan_stopped_rtnl
From: Eliad Peller <eliad@xxxxxxxxxx>
commit 792e6aa7a15ea0fb16f8687e93caede1ea9118c7 upstream.
Add locked-version for cfg80211_sched_scan_stopped.
This is used for some users that might want to
call it when rtnl is already locked.
Fixes: d43c6b6 ("mac80211: reschedule sched scan after HW restart")
