[PATCH 5.17 362/772] ASoC: samsung: Fix refcount leak in aries_audio_probe
From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 17:06:45 EST
From: Miaoqian Lin <linmq006@xxxxxxxxx>
[ Upstream commit bf4a9b2467b775717d0e9034ad916888e19713a3 ]
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.
