Subject: [PATCH net-next] net: toshiba: fix return type of ndo_start_xmit function
Date: Wed, 19 Sep 2018 18:32:39 +0800 [thread overview]
Message-ID: <20180919103240.27708-1-yuehaibing@huawei.com> (raw)
The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.
Found by coccinelle.
