Subject: [PATCH net-next] net: ethernet: mediatek: enhance with avoiding superfluous assignment inside mtk_get_ethtool_stats
Date: Tue, 20 Sep 2016 11:26:48 +0800	[thread overview]
Message-ID: <1474342008-22496-1-git-send-email-sean.wang@mediatek.com> (raw)

From: Sean Wang <sean.wang@mediatek.com>

data_src is unchanged inside the loop, so this patch moves
the assignment to outside the loop to avoid unnecessarily
assignment
