Description

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

PCI: microchip: Fix refcount leak in mc_pcie_init_irq_domains()

of_get_next_child() returns a node pointer with refcount incremented, so we should use of_node_put() on it when we don't need it anymore.

mc_pcie_init_irq_domains() only calls of_node_put() in the normal path, missing it in some error paths. Add missing of_node_put() to avoid refcount leak.
