Subject: [PATCH 12/15] net: gemini: Fix missing free_netdev() in error path of
gemini_ethernet_port_probe()
Git-commit: cf96d977381d4a23957bade2ddf1c420b74a26b6
Patch-mainline: v5.9-rc2
References: git-fixes
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")
