Subject: [PATCH] pinctrl: nomadik: Add missing of_node_put() in nmk_pinctrl_probe
Date: Mon, 7 Mar 2022 11:51:16 +0000 [thread overview]
Message-ID: <20220307115116.25316-1-linmq006@gmail.com> (raw)
This node pointer is returned by of_parse_phandle() with refcount
incremented in this function. Calling of_node_put() to avoid
the refcount leak.
Fixes: 32e67eee670e ("pinctrl: nomadik: Allow prcm_base to be extracted from Device Tree")
