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
17755 1312 16 19083 4a8b drivers/input/input.o
File size After adding 'const':
text data bss dec hex filename
17947 1120 16 19083 4a8b drivers/input/input.o
