From: Alex Chiang Date: Thu, 18 Jun 2009 01:03:57 +0000 (-0600) Subject: PCI: drivers/pci/slot.c should depend on CONFIG_SYSFS X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=268a03a42d3377d5fb41e6e7cbdec4e0b65cab2e;p=linux-beck.git 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.
