From b8d91399775c55162073bb2aca061ec42e3d4bc1 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Fri, 3 Jun 2022 17:32:38 +0400 Subject: [PATCH] net: ethernet: bgmac: Fix refcount leak in bcma_mdio_mii_register of_get_child_by_name() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
