Subject: [PATCH v2] ASoC: mediatek: mt8173-rt5650: Fix refcount leak in mt8173_rt5650_dev_probe
Date: Fri, 3 Jun 2022 16:42:41 +0400 [thread overview]
Message-ID: <20220603124243.31358-1-linmq006@gmail.com> (raw)
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when not need anymore.
Fix refcount leak in some error paths.
Fixes: 0f83f9296d5c ("ASoC: mediatek: Add machine driver for ALC5650 codec")
