[PATCH] PCI: imx: fix device node reference leak in imx_pcie_probe
From: Miaoqian Lin <hidden>
Date: 2025-09-03 13:52:00
Also in:
imx, linux-arm-kernel, linux-pci, lkml
Subsystem:
pci driver for imx6, pci native host bridge and endpoint drivers, pci subsystem, the rest · Maintainers:
Richard Zhu, Lucas Stach, Lorenzo Pieralisi, Krzysztof Wilczyński, Manivannan Sadhasivam, Bjorn Helgaas, Linus Torvalds
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.
