ACPI / power: constify attribute_group structures
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 4622 304 8 4934 1346 drivers/acpi/power.o File size After adding 'const': text data bss dec hex filename 4846 80 8 4934 1346 drivers/acpi/power.o Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Rafael J.
