[PATCH net v2] net: gemini: Fix missing free_netdev() in error path of gemini_ethernet_port_probe()
From: Wang Hai
Date: Tue Aug 18 2020 - 22:35:28 EST
Replace alloc_etherdev_mq with devm_alloc_etherdev_mqs. In this way,
when probe fails, netdev can be freed automatically.
Fixes: 4d5ae32f5e1e ("net: ethernet: Add a driver for Gemini gigabit ethernet")
