Subject: [PATCH AUTOSEL 5.4 10/29] net: lantiq_etop: Fix return type for implementation of ndo_start_xmit
From: GUO Zihua <guozihua@...wei.com>
[ Upstream commit c8ef3c94bda0e21123202d057d4a299698fa0ed9 ]
Since Linux now supports CFI, it will be a good idea to fix mismatched
return type for implementation of hooks. Otherwise this might get
cought out by CFI and cause a panic.
ltq_etop_tx() would return either NETDEV_TX_BUSY or NETDEV_TX_OK, so
change the return type to netdev_tx_t directly.
