+From e5d00646a207c4e9da254283eee2d278de338394 Mon Sep 17 00:00:00 2001

+Subject: [RFC 12/12] ath9k: fix null pointer dereference in ani monitor code
+
+In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only
+if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using 'ahp->ah_curani'
+unconditionally, and it will cause a NULL pointer dereference on AR9100.
