[PATCH 5.10 48/70] net: cpsw: add missing of_node_put() in cpsw_probe_dt()

[Greg Kroah-Hartman]

From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

commit 95098d5ac2551769807031444e55a0da5d4f0952 upstream.

'tmp_node' need be put before returning from cpsw_probe_dt(),
so add missing of_node_put() in error path.

Fixes: ed3525eda4c4 ("net: ethernet: ti: introduce cpsw switchdev based driver part 1 - dual-emac")
