Subject: [PATCH AUTOSEL 4.14 019/109] net: toshiba: fix return type of ndo_start_xmit function
Date: Sat,  9 Nov 2019 21:44:11 -0500	[thread overview]
Message-ID: <20191110024541.31567-19-sashal@kernel.org> (raw)
In-Reply-To: <20191110024541.31567-1-sashal@kernel.org>

From: YueHaibing <yuehaibing@huawei.com>

[ Upstream commit bacade822524e02f662d88f784d2ae821a5546fb ]

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.
