Subject: [PATCH] net: ethernet: mvneta: Fix error handling in mvneta_probe
Date: Sun, 20 Dec 2020 16:29:30 +0800
Message-ID: <20201220082930.21623-1-dinghao.liu@zju.edu.cn> (raw)

When mvneta_port_power_up() fails, we should execute
cleanup functions after label err_netdev to avoid memleak.

Fixes: 41c2b6b4f0f80 ("net: ethernet: mvneta: Add back interface mode validation")
