ERROR: modpost: "devm_platform_ioremap_resource" [drivers/phy/starfive/phy-jh7110-pcie.ko] undefined!

I can not find this error. devm_platform_ioremap_resource is an exported symbol

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.
