Subject: [PATCH 6/8] s390: raw3270: constify attribute_group structures.
Date: Wed, 19 Jul 2017 12:39:15 +0530 [thread overview]
Message-ID: <1500448157-24668-7-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1500448157-24668-1-git-send-email-arvind.yadav.cs@gmail.com>
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
8069 816 16 8901 22c5 drivers/s390/char/raw3270.o
File size After adding 'const':
text data bss dec hex filename
8133 752 16 8901 22c5 drivers/s390/char/raw3270.o
