Subject: [PATCH AUTOSEL 5.15 27/46] net: ethernet: litex: Fix return type of liteeth_start_xmit
Date: Sun,  9 Oct 2022 18:18:52 -0400	[thread overview]
Message-ID: <20221009221912.1217372-27-sashal@kernel.org> (raw)
In-Reply-To: <20221009221912.1217372-1-sashal@kernel.org>

From: Nathan Huckleberry <nhuck@google.com>

[ Upstream commit 40662333dd7c64664247a6138bc33f3974e3a331 ]

The ndo_start_xmit field in net_device_ops is expected to be of type
netdev_tx_t (*ndo_start_xmit)(struct sk_buff *skb, struct net_device *dev).

The mismatched return type breaks forward edge kCFI since the underlying
function definition does not match the function hook definition.

The return type of liteeth_start_xmit should be changed from int to
netdev_tx_t.
