[PATCH v3] staging: unisys: visorbus: Constify attribute_group structures.

Show all headers | View raw

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.
