Subject: [PATCH 2/3] char: tpm: constify attribute_group structures.
Date: Wed, 2 Aug 2017 16:50:14 +0530 [thread overview]
Message-ID: <1501672814-2995-1-git-send-email-arvind.yadav.cs@gmail.com> (raw)
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.
