  [PATCH 7/8] s390: tape_core: constify attribute_group structures. Arvind Yadav <arvind.yadav.cs@gmail.com> - 2017-07-19 09:20 +0200

#1691053 — [PATCH 7/8] s390: tape_core: constify attribute_group structures.

attribute_group are not supposed to change at runtime. All functions
working with attribute_group 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
  11511	    656	     16	  12183	   2f97	drivers/s390/char/tape_core.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  11575	    592	     16	  12183	   2f97	drivers/s390/char/tape_core.o
