Subject: [PATCH] wireless: iwlegacy: constify attribute_group structures.
Date: Mon, 10 Jul 2017 15:12:53 +0530	[thread overview]
Message-ID: <> (raw)

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work
with const attribute_group. So mark the non-const structs as const.
