  [PATCH v2 5/7] x86: ksysfs: constify attribute_group structures. Arvind Yadav <arvind.yadav.cs@gmail.com> - 2017-07-20 13:40 +0200

#1692828 — [PATCH v2 5/7] x86: ksysfs: constify attribute_group structures.

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.
