[PATCH 5.4 099/107] net: gemini: Fix missing free_netdev() in error path of gemini_ethernet_port_probe()

[Greg Kroah-Hartman]

From: Wang Hai <wanghai38@xxxxxxxxxx>

[ Upstream commit cf96d977381d4a23957bade2ddf1c420b74a26b6 ]

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")
