Subject: [PATCH] platform/x86: alienware-wmi: constify attribute_group
structures.
Git-commit: 4b7942d8d1ced3c82495953cb0bb90e7de6dbba6
References: git-fixes
Patch-mainline: v4.13-rc1
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':
