When CONFIG_EEH=y and CONFIG_VFIO_SPAPR_EEH=n, build fails with the
following:
drivers/vfio/pci/vfio_pci.o: In function `.vfio_pci_release':
vfio_pci.c:(.text+0xa98): undefined reference to `.vfio_spapr_pci_eeh_release'
drivers/vfio/pci/vfio_pci.o: In function `.vfio_pci_open':
vfio_pci.c:(.text+0x1420): undefined reference to `.vfio_spapr_pci_eeh_open'
In this case, vfio_pci.c should use the empty definitions of
vfio_spapr_pci_eeh_open and vfio_spapr_pci_eeh_release functions.
This patch fixes it by guarding these function definitions with
CONFIG_VFIO_SPAPR_EEH, the symbol that controls whether vfio_spapr_eeh.c is
built, which is where the non-empty versions of these functions are. We need to
make use of IS_ENABLED() macro because CONFIG_VFIO_SPAPR_EEH is a tristate
option.
This issue was found during a randconfig build. Logs are here:
