attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by <linux/device.h> work with const attribute_group. So mark the non-const structs as const.

File size After adding 'const': text data bss dec hex filename 1035 544 0 1579 62b sound/pci/hda/hda_sysfs.o
