cfg80211: sched_scan_mtx lock in cfg80211_conn_work()
Introduced in f9f475292dbb0e7035fb6661d1524761ea0888d9 ("cfg80211: always check for scan end on P2P device") cfg80211_conn_scan() which requires sched_scan_mtx to be held can be called from cfg80211_conn_work(). Without this we are hitting multiple warnings like the following: WARNING: at net/wireless/sme.c:88 cfg80211_conn_scan+0x1dc/0x3a0 [cfg80211]() Hardware name: 0578A21 Modules linked in: ...
