5.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Hai <wanghai38@xxxxxxxxxx>
[ Upstream commit c401ed1c709948e57945485088413e1bb5e94bd1 ]
The bcm_sysport_xmit() returns NETDEV_TX_OK without freeing skb
in case of dma_map_single() fails, add dev_kfree_skb() to fix it.
Fixes: 80105befdb4b ("net: systemport: add Broadcom SYSTEMPORT Ethernet MAC driver")
