[PATCH 3/3] PCI: hotplug: constify attribute_group structures.

[Arvind Yadav]

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

File size before:
   text    data     bss     dec     hex filename
    418     160       8     586     24a drivers/pci/hotplug/rpadlpar_sysfs.o

File size After adding 'const':
   text    data     bss     dec     hex filename
    482      96       8     586     232 drivers/pci/hotplug/rpadlpar_sysfs.o
