[PATCH 5.10 203/452] ASoC: mxs-saif: Fix refcount leak in mxs_saif_probe

From: Greg Kroah-Hartman
Date: Tue Jun 07 2022 - 13:44:50 EST


From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit 2be84f73785fa9ed6443e3c5b158730266f1c2ee ]

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.

Fixes: 08641c7c74dd ("ASoC: mxs: add device tree support for mxs-saif")
