Subject: [PATCH] bus: arm-integrator-lm: Fix refcount leak in integrator_ap_lm_probe
Date: Mon, 23 May 2022 19:34:09 +0400 [thread overview]
Message-ID: <20220523153409.22949-1-linmq006@gmail.com> (raw)
of_find_matching_node() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Add missing of_node_put() to avoid refcount leak.
Fixes: ccea5e8a5918 ("bus: Add driver for Integrator/AP logic modules")
