I don't understand this. In drivers/pci/Kconfig, we have:
config PCI_IOV
depends on PCI
and in drivers/crypto/qat/Kconfig, dd0f368398ea adds:
config CRYPTO_DEV_QAT_DH895xCCVF
select PCI_IOV
And apparently it's possible to end up with a .config with
CONFIG_PCI_IOV=y but CONFIG_PCI is not set? That seems wrong, since
we declared that PCI_IOV depends on PCI. Does select ignore that
dependency somehow?
