From 071d068b89e95d1b078aa6bbcb9d0961b77d6aa1 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Mon, 2 Jan 2023 12:28:10 +0400 Subject: irqchip/alpine-msi: Fix refcount leak in alpine_msix_init_domains of_irq_find_parent() returns a node pointer with refcount incremented, We should use of_node_put() on it when not needed anymore. Add missing of_node_put() to avoid refcount leak.
