+Subject: [PATCH] ath9k: flush bt profile whenever it is requested
+
+Before processing BT profiles or status messages, check whether
+it is requested to flush BT profile. Otherwise it might increase
+number of BT profiles that affects the WLAN performance. Also
+flush the profiles when MCI is recovering from broken rx. After
+flushing BT profiles, query BT topology to refetch them.

+Subject: [PATCH] ath9k: fill led_pin before drv_start
+
+Ensure that led pin is filled and set to OFF before starting
+the driver. With recent changes, drv_start is being called even
+before led_init is being completed. This is causing led is always
+OFF on driver load when the interface is UP. This patch splits the
+led init and fills the led pin before register hw.
