Subject: [PATCH] cpufreq: zynq: Fix refcount leak in zynq_get_revision
Date: Sun, 5 Jun 2022 12:28:07 +0400 [thread overview]
Message-ID: <20220605082807.21526-1-linmq006@gmail.com> (raw)
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.
Fixes: 00f7dc636366 ("ARM: zynq: Add support for SOC_BUS")
