+Subject: [PATCH] ath9k: Fix RoC expiration
+
+mac80211 has to be notified when a RoC period
+expires in the driver. In MCC mode, since the
+offchannel/RoC timer is set with the requested
+duration, ieee80211_remain_on_channel_expired() needs
+to be called when the timer expires.
+
+But, currently it is done after we move back to
+the operating channel. This is incorrect - fix this
+by calling ieee80211_remain_on_channel_expired() when
+the RoC timer expires and in ath_roc_complete() when
+the RoC request is aborted.
