I asked Arnd about this since the error confused me too. Arnd pointed
out that this "allmodconfig" isn't really allmodconfig as PCI is
disabled. On s390, CONFIG_HAS_IOMEM depends on PCI and thus none of
this devres stuff is usable without it. He suggested that you make the
driver depend on USB_SUPPORT, which in turn depends on HAS_IOMEM.

Cheers,
Conor.
