Subject: net: rswitch: Fix return value in rswitch_start_xmit()
X-Git-Tag: v6.6.7~302
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=940af3fee268568a96511108c1b610227696cd69;p=platform%2Fkernel%2Flinux-starfive.git

net: rswitch: Fix return value in rswitch_start_xmit()

[ Upstream commit 1aaef8634a20b322c82e84f12a9b6aec1e2fd4fa ]

This .ndo_start_xmit() function should return netdev_tx_t value,
not -ENOMEM. So, fix it.
