[PATCH 5.15 061/135] net: ethernet: mediatek: add missing of_node_put() in mtk_sgmii_init()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Yang Yingliang <yangyingliang@xxxxxxxxxx>

commit ff5265d45345d01fefc98fcb9ae891b59633c919 upstream.

The node pointer returned by of_parse_phandle() with refcount incremented,
so add of_node_put() after using it in mtk_sgmii_init().
