   4 Subject: [PATCH] net: ethernet: mtk_eth_soc: fix resource leak in error path
   5
   6 In mtk_probe(), when mtk_ppe_init() or mtk_eth_offload_init() failed,
   7 mtk_mdio_cleanup() isn't called. Fix it.
   8
   9 Fixes: ba37b7caf1ed ("net: ethernet: mtk_eth_soc: add support for initializing the PPE")
  10 Fixes: 502e84e2382d ("net: ethernet: mtk_eth_soc: add flow offloading support")
