Subject: [PATCH] soc: qcom: smp2p: Fix missing of_node_put() in smp2p_parse_ipc
Date: Tue, 8 Mar 2022 07:19:42 +0000 [thread overview]
Message-ID: <20220308071942.22942-1-linmq006@gmail.com> (raw)
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
Fixes: 50e99641413e ("soc: qcom: smp2p: Qualcomm Shared Memory Point to Point")
