Subject: PM: hibernate: constify attribute_group structures.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=59494fe2c89e46e85d83de9bc45dd1d528955c49;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

PM: hibernate: constify attribute_group structures.

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
