[PATCH] PM: hibernate: constify attribute_group structures.

From: Arvind Yadav
Date: Thu Jun 29 2017 - 07:29:40 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
6332 488 308 7128 1bd8 kernel/power/hibernate.o

File size After adding 'const':
text data bss dec hex filename
6396 424 308 7128 1bd8 kernel/power/hibernate.o
