From: Johannes Berg <johannes.berg@xxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit d2722f8b87fb172ff2f31d3a2816b31d58678d40 upstream.
The bss struct might be freed in ieee80211_rx_bss_put(),
so we shouldn't use it afterwards.
Fixes: 817cee7675237 ("mac80211: track AP's beacon rate and give it to the driver")
