+    ath9k: Fix TX power calculation
+    
+    The commit, "ath9k_hw: Fix incorrect Tx control power in AR9003 template"
+    fixed the incorrect values in the eeprom templates, but if
+    boards have already been calibrated with incorrect values,
+    they would still be using the wrong TX power. Fix this by assigning
+    a default value in such cases.
