[PATCH] imon: constify attribute_group structures

From: Amitoj Kaur Chawla
Date: Fri Aug 04 2017 - 21:51:43 EST


Functions working with attribute_groups provided by <linux/sysfs.h>
work with const attribute_group. These attribute_group structures do not
change at runtime so mark them as const.

File size before:
text data bss dec hex filename
36981 16776 960 54717 d5bd drivers/media/rc/imon.o

File size after:
text data bss dec hex filename
37173 16584 960 54717 d5bd drivers/media/rc/imon.o

This change was made with the help of Coccinelle.
