From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

[ Upstream commit c45231a7668d6b632534f692b10592ea375b55b0 ]

'netdev' is a managed resource allocated in the probe using
'devm_alloc_etherdev()'.
It must not be freed explicitly in the remove function.

Fixes: ee7da21ac4c3 ("net: Add driver for LiteX's LiteETH network interface")
