From d1ff2559cef0f6f8d97fba6337b28adb10689e16 Mon Sep 17 00:00:00 2001 From: Miaoqian Lin Date: Sun, 5 Jun 2022 12:28:07 +0400 Subject: cpufreq: zynq: Fix refcount leak in zynq_get_revision of_find_compatible_node() returns a node pointer with refcount incremented, we should use of_node_put() on it when done. Add missing of_node_put() to avoid refcount leak.
