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 before:
   text	   data	    bss	    dec	    hex	filename
   6932	   1016	     48	   7996	   1f3c	drivers/platform/x86/alienware-wmi.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   7060	    888	     48	   7996	   1f64	drivers/platform/x86/alienware-wmi.o
