Subject: [PATCH] soc: qcom: smsm: Fix missing of_node_put() in smsm_parse_ipc
Git-commit: aad66a3c78da668f4506356c2fdb70b7a19ecc76
Patch-mainline: v5.19-rc1
References: git-fixes
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
Fixes: c97c4090ff72 ("soc: qcom: smsm: Add driver for Qualcomm SMSM")
