Subject: [PATCH] platform/x86: asus-wmi: constify attribute_group structures.
Git-commit: e90d9ba837b3b779644613a3b9e4845a0cd302f2
Patch-mainline: v4.13-rc1
References: bsc#1126285

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
  13140	    840	      1	  13981	   369d	drivers/platform/x86/asus-wmi.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  13268	    712	      1	  13981	   368d	drivers/platform/x86/asus-wmi.o
