Subject: [PATCH AUTOSEL 4.9 28/50] net: allwinner: Fix use correct return type for ndo_start_xmit()
Date: Mon,  8 Jun 2020 19:26:18 -0400	[thread overview]
Message-ID: <20200608232640.3370262-28-sashal@kernel.org> (raw)
In-Reply-To: <20200608232640.3370262-1-sashal@kernel.org>

From: Yunjian Wang <wangyunjian@huawei.com>

[ Upstream commit 09f6c44aaae0f1bdb8b983d7762676d5018c53bc ]

The method ndo_start_xmit() returns a value of type netdev_tx_t. Fix
the ndo function to use the correct type. And emac_start_xmit() can
leak one skb if 'channel' == 3.
