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 ofnode_put() 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 ofnodeput() to avoid refcount leak.
