while building without CONFIG_SYSFS, fails as below:
drivers/pci/controller/pci-hyperv.o: In function 'hv_pci_assign_slots': pci-hyperv.c:(.text+0x40a): undefined reference to 'pci_create_slot' drivers/pci/controller/pci-hyperv.o: In function 'pci_devices_present_work': pci-hyperv.c:(.text+0xc02): undefined reference to 'pci_destroy_slot' drivers/pci/controller/pci-hyperv.o: In function 'hv_pci_remove': pci-hyperv.c:(.text+0xe50): undefined reference to 'pci_destroy_slot' drivers/pci/controller/pci-hyperv.o: In function 'hv_eject_device_work': pci-hyperv.c:(.text+0x11f9): undefined reference to 'pci_destroy_slot'
Select SYSFS while PCI_HYPERV is set to fix this.
