Subject: [PATCH net-next] net: sun: fix return type of ndo_start_xmit function
Date:   Wed, 19 Sep 2018 19:21:32 +0800
Message-ID: <20180919112132.26616-1-yuehaibing@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, but the implementation in this
driver returns an 'int'.

Found by coccinelle.
