From 110a1fcb6c4d55144d8179983a475f17a1d6f832 Mon Sep 17 00:00:00 2001 From: Liang He Date: Fri, 1 Jul 2022 21:17:50 +0800 Subject: powerpc/pci_dn: Add missing of_node_put() In pci_add_device_node_info(), use of_node_put() to drop the reference to 'parent' returned by of_get_parent() to keep refcount balance.
