From a5a041b6b50bcaf96f96e5db4850d11006d61d26 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Thu, 29 Jun 2017 16:07:01 +0530 Subject: [PATCH] ALSA: hda: 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.
