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

From: Arvind Yadav
Date: Wed Jul 19 2017 - 03:10:31 EST


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
