+Subject: [PATCH] ath9k_common: always update value in
+ ath9k_cmn_update_txpow
+
+In some cases the limit may be the same as reg->power_limit, but the
+actual value that the hardware uses is not up to date. In that case, a
+wrong value for current tx power is tracked internally.
+Fix this by unconditionally updating it.
