From 7b346dac731361d45ef173f66df3a6509fd3b865 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Thu, 29 Sep 2016 20:18:54 +0530 Subject: [PATCH] Staging: dgnc: constify attribute_group structures Check for attribute_group structures that are only passed as a second argument to the functions sysfs_remove_group and sysfs_create_group. As these arguments are constant so, attribute_group structures having this property can also be made constant.
