Subject: [PATCH] ASoC: samsung: Fix refcount leak in aries_audio_probe
Date: Thu, 12 May 2022 08:38:28 +0400 [thread overview]
Message-ID: <20220512043828.496-1-linmq006@gmail.com> (raw)
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
If extcon_find_edev_by_node() fails, it doesn't call of_node_put()
Calling of_node_put() after extcon_find_edev_by_node() to fix this.
Fixes: 7a3a7671fa6c ("ASoC: samsung: Add driver for Aries boards")
