[ath9k-devel] [RFC] ath9k: Stop the BT timers before disabling BT

[Mohammed Shafi Shajakhan]

From: Mohammed Shafi Shajakhan <mohammed@qca.qualcomm.com>

Stop the BT timers 'period_timer' and 'no_stomp_timer'.
Both these timers can change the BT stomp type especially
for AR9462 chipsets eventhough we had called ath9k_hw_btcoex_disable.
ath9k_hw_btcoex_disable->ath9k_hw_btcoex_bt_stomp(ah,
ATH_BTCOEX_STOMP_NONE). Will do some more analysis before sending
at as a patch.
