Subject: [PATCH] PCI: imx: fix device node reference leak in imx_pcie_probe
Date: Wed, 3 Sep 2025 21:51:50 +0800 [thread overview]
Message-ID: <20250903135150.2527259-1-linmq006@gmail.com> (raw)
As the doc of of_parse_phandle() states:
"The device_node pointer with refcount incremented. Use
* of_node_put() on it when done."
Add missing of_node_put() after of_parse_phandle() call to properly
release the device node reference.
Found via static analysis.
Fixes: 1df82ec46600 ("PCI: imx: Add workaround for e10728, IMX7d PCIe PLL failure")
