Hi all,

After merging the pci tree, today's linux-next build (sparc defconfig)
produced this warning:

In file included from /home/sfr/next/next/include/linux/pci.h:37,
                 from /home/sfr/next/next/drivers/pci/pci-sysfs.c:19:
/home/sfr/next/next/include/linux/device.h:199:33: warning: 'dev_attr_boot_display' defined but not used [-Wunused-variable]
  199 |         struct device_attribute dev_attr_##_name = __ATTR_RO(_name)
      |                                 ^~~~~~~~~
