+Subject: [PATCH] ath9k_hw: fix duplicate (and partially wrong) definition
+ of AR_CH0_THERM
+
+AR_PHY_65NM_CH0_THERM and AR_CH0_THERM were supposed to refer to the
+same register, however they had different SREV checks.
+
+Remove the duplicate and use the checks. Since there were other SREV
+checks present in the only place that uses this, this will probaby not
+affect runtime behavior.
