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
5147 560 0 5707 164b panel-sony-acx565akm.o
File size After adding 'const':
text data bss dec hex filename
5211 496 0 5707 164b panel-sony-acx565akm.o
