> adapter.
> The cxl_pci_to_afu API is extended to work with peer PCI devices,
> retrieving the peer AFU from the PHB. This API may also now return an
> error if it is called on a PCI device that is not associated with either
> a cxl vPHB or a peer PCI device to an AFU, and this error is propagated
