Subject: [PATCH] PCI: imx6: Add missing of_node_put() in imx6_pcie_probe
Date:   Tue,  8 Mar 2022 02:29:29 +0000
Message-Id: <20220308022929.30002-1-linmq006@gmail.com>
Precedence: bulk

The device_node pointer is returned by of_parse_phandle()  with refcount
incremented. We should use of_node_put() on it when done.

Fixes: 1df82ec46600 ("PCI: imx: Add workaround for e10728, IMX7d PCIe PLL failure")
