In the Linux kernel, the following vulnerability has been resolved:

PCI: mediatek: Fix refcount leak in mtk_pcie_subsys_powerup()

The of_find_compatible_node() function returns a node pointer with
refcount incremented, We should use of_node_put() on it when done
Add the missing of_node_put() to release the refcount.
