PCI: drivers/pci/slot.c should depend on CONFIG_SYSFS
There is no way to interact with a physical PCI slot without
sysfs, so encode the dependency and prevent this build error:
drivers/pci/slot.c: In function 'pci_hp_create_module_link':
drivers/pci/slot.c:327: error: 'module_kset' undeclared
This patch _should_ make pci-sysfs.o depend on CONFIG_SYSFS too,
but we cannot (yet) because the PCI core merrily assumes the
existence of sysfs:
drivers/built-in.o: In function `pci_bus_add_device':
drivers/pci/bus.c:89: undefined reference to `pci_create_sysfs_dev_files'
drivers/built-in.o: In function `pci_stop_dev':
drivers/pci/remove.c:24: undefined reference to `pci_remove_sysfs_dev_files'
So do the minimal bit for now and figure out how to untangle it
later.
