Subject: [PATCH] ASoC: audio-graph-card: Add of_node_put() in fail path
Date: Thu, 21 Jul 2022 22:43:08 +0800	[thread overview]
Message-ID: <20220721144308.1301587-1-windhl@126.com> (raw)

In asoc_simple_parse_dai(), we should call of_node_put() for the
reference returned by of_graph_get_port_parent() in fail path.

Fixes: ae30a694da4c ("ASoC: simple-card-utils: add asoc_simple_card_parse_dai()")
