Subject: [PATCH] rpmsg: qcom_smd: Fix refcount leak in qcom_smd_parse_edge
Date: Wed, 11 May 2022 16:07:37 +0400 [thread overview]
Message-ID: <20220511120737.57374-1-linmq006@gmail.com> (raw)
of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Fixes: 53e2822e56c7 ("rpmsg: Introduce Qualcomm SMD backend")
