From: Ajay Singh <ajay.kathat@xxxxxxxxxxxxx>
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.
Fixes: 2fe8ef106238 ("cfg80211: change netdev registration/unregistration semantics")
