Subject: ath9k: Use lockless variant to initialize RX fifo
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5d07cca2128c214ea6029a6b65082e642ee7355e;p=deliverable%2Flinux.git

ath9k: Use lockless variant to initialize RX fifo

Since the rx_fifo queue is accessed only using the various
lockless SKB queue routines, there is no need to initialize
the lock and __skb_queue_head_init() can be used.
