Subject: [PATCH -next] net: cpsw: add missing of_node_put() in cpsw_probe_dt()
Date: Tue, 26 Apr 2022 20:47:57 +0800 [thread overview]
Message-ID: <20220426124757.373587-1-yangyingliang@huawei.com> (raw)
If devm_kcalloc() fails, 'tmp_node' should be put in cpsw_probe_dt().
Fixes: ed3525eda4c4 ("net: ethernet: ti: introduce cpsw switchdev based driver part 1 - dual-emac")
