+Subject: [PATCH] ath9k: Fix programming of minCCA power threshold
+
+The function ar9003_hw_apply_minccapwr_thresh takes as second parameter not
+a pointer to the channel but a boolean value describing whether the channel
+is 2.4GHz or not. This broke (according to the origin commit) the ETSI
+regulatory compliance on 5GHz channels.
+
+Fixes: 3533bf6b15a0 ("ath9k: Fix regulatory compliance")
