In the Linux kernel, the following vulnerability has been resolved: PCI: microchip: Fix refcount leak in mcpcieinitirqdomains() ofgetnextchild() returns a node pointer with refcount incremented, so we should use ofnodeput() on it when we don't need it anymore. mcpcieinitirqdomains() only calls ofnodeput() in the normal path, missing it in some error paths. Add missing ofnode_put() to avoid refcount leak.
