cpu/hotplug: 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 12582 15361 20 27963 6d3b kernel/cpu.o File size After adding 'const': text data bss dec hex filename 12710 15265 20 27995 6d5b kernel/cpu.o Signed-off-by: Arvind Yadav <[email protected]> Cc: Linus Torvalds <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Thomas Gleixner <[email protected]> Cc: [email protected] Cc: [email protected] Cc: [email protected] Cc: [email protected] Link: http://lkml.kernel.org/r/f9079e94e12b36d245e7adbf67d312bc5d0250c6.1498737970.git.arvind.yadav.cs@gmail.com Signed-off-by: Ingo Molnar <[email protected]>
