From af87a469695dc2b2419b2fdff0bf41db5265b325 Mon Sep 17 00:00:00 2001 From: Liang He Date: Fri, 1 Jul 2022 20:41:12 +0800 Subject: [PATCH] mips: cavium-octeon: Fix missing of_node_put() in octeon2_usb_clocks_start [ Upstream commit 7a9f743ceead60ed454c46fbc3085ee9a79cbebb ] We should call of_node_put() for the reference 'uctl_node' returned by of_get_parent() which will increase the refcount. Otherwise, there will be a refcount leak bug.
