+Subject: [PATCH] ath9k: Turn ath_txq_lock/unlock() into static inlines.
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+These are one-line functions that just call spin_lock/unlock_bh(); turn
+them into static inlines to avoid the function call overhead.
