Subject: [PATCH] rpmsg: qcom_smd: Fix refcount leak in qcom_smd_parse_edge
Git-commit: 65382585f067d4256ba087934f30f85c9b6984de
Patch-mainline: v6.0-rc1
References: git-fixes
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")
