From bc1bb362334ebc4c65dd4301f10fb70902b3db7d Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Mon, 10 Jul 2017 15:50:15 -0700 Subject: [PATCH] zram: constify attribute_group structures. attribute_groups are not supposed to change at runtime. All functions working with attribute_groups provided by work with const attribute_group. So mark the non-const structs as const.
