Subject[PATCH] ACPI / DPTF: 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
904 496 0 1400 578 drivers/acpi/dptf/dptf_power.o

File size After adding 'const':
text data bss dec hex filename
944 432 0 1376 560 drivers/acpi/dptf/dptf_power.o
