[PATCH 0/3] constify firmware attribute_group structures.

[PATCH 0/3] constify firmware attribute_group structures.

[Arvind Yadav]

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.

If Douglas doesn't mind, I will take this trough the EFI tree
