[PATCH v4] staging: unisys: visorbus: Constify attribute_group structures.

From: Arvind Yadav
Date: Tue Jul 18 2017 - 04:11:45 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.
