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 Link: http://lkml.kernel.org/r/aa224b3cc923fdbb3edd0c41b2c639c85408c9e8.1498737347.git.arvind.yadav.cs@gmail.com Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Acked-by: Kees Cook <keescook@chromium.org> Cc: Russell King <rmk+kernel@arm.linux.org.uk> Cc: Dave Young <dyoung@redhat.com> Cc: Hari Bathini <hbathini@linux.vnet.ibm.com> Cc: Petr Tesarik <ptesarik@suse.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
