The hw_scan callback breaks the auto AP selection code in ieee80211_sta.c.
No in-tree drivers use it either. This patch removes it.
The auto AP selection code is broken because ieee80211_sta_config_auth wasn't selecting a network if the RSSI was negative.)
Thanks,

[PATCH] Fix ieee80211_sta_config_auth to select networks if rssi < 0
The rssi check was against the top_rssi being less than the network
rssi. However, 0 is higher than all negative rssi, so if an adapter
returned negative rssi values, auto AP selection would never work.
This patch changes behavior such if no network is currently selected it
ignores the rssi comparison and picks the network that matches all other criteria.
