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

From: Arvind Yadav
Date: Tue Jul 11 2017 - 05:29:20 EST


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
