[patch 080/115] kernel/ksysfs.c: constify attribute_group structures.

[akpm]

From: Arvind Yadav <arvind.yadav.cs@gmail.com>
Subject: kernel/ksysfs.c: 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
   1120	    544	     16	   1680	    690	kernel/ksysfs.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   1160	    480	     16	   1656	    678	kernel/ksysfs.o
