Subject: [PATCH] cpufreq: intel_pstate: constify attribute_group structures.
Date: Mon, 3 Jul 2017 13:40:33 +0530 [thread overview]
Message-ID: <229e26ffc410cf4908c55ca0cb13906fd4bf4cf5.1499068985.git.arvind.yadav.cs@gmail.com> (raw)
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 After adding 'const':
