Subject: [PATCH] pinctrl: mediatek: Fix missing of_node_put() in mtk_pctrl_init
Date: Tue,  8 Mar 2022 07:11:54 +0000	[thread overview]
Message-ID: <20220308071155.21114-1-linmq006@gmail.com> (raw)

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

Fixes: a6df410d420a ("pinctrl: mediatek: Add Pinctrl/GPIO driver for mt8135.")
