  [PATCH 2/3] char: tpm: constify attribute_group structures. Arvind Yadav <arvind.yadav.cs@gmail.com> - 2017-08-02 13:30 +0200

#1702021 — [PATCH 2/3] char: tpm: 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.
