Subject: [PATCH 06/26] hwtracing: coresight: constify attribute_group structures.
Date: Wed, 2 Aug 2017 10:22:00 -0600 [thread overview]
Message-ID: <1501690940-4137-7-git-send-email-mathieu.poirier@linaro.org> (raw)
In-Reply-To: <1501690940-4137-1-git-send-email-mathieu.poirier@linaro.org>
From: Arvind Yadav <arvind.yadav.cs@gmail.com>
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.
File size before:
text data bss dec hex filename
2573 288 296 3157 c55 coresight-etm-perf.o
File size After adding 'const':
text data bss dec hex filename
2613 224 296 3133 c3d coresight-etm-perf.o
