[ Upstream commit 868f0e28290c7a33e8cb79bfe97ebdcbb756e048 ]
Monitor(mon.) interface is used for handling the AP mode and 'ieee80211_ptr' reference is not getting set for it. Like earlier implementation, use register_netdevice() instead of cfg80211_register_netdevice() which expects valid 'ieee80211_ptr' reference to avoid the possible crash.
