Subject[PATCH 2/7] platform/x86: compal-laptop: constify attribute_group structures.
Date
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
6781 6144 34 12959 329f drivers/platform/x86/compal-laptop.o

File size After adding 'const':
text data bss dec hex filename
6845 6080 34 12959 329f drivers/platform/x86/compal-laptop.o
