[PATCH 2/8] s390: zcrypt_card: constify attribute_group structures.
From: Arvind Yadav
Date: Wed Jul 19 2017 - 03:11:25 EST
attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.

File size After adding 'const':
text data bss dec hex filename
