[PATCH] staging: unisys: visorbus_main: constify attribute_group structures

From: Amitoj Kaur Chawla
Date: Tue Jul 25 2017 - 18:45:13 EST


Functions working with attribute_groups provided by <linux/device.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
14216 7304 832 22352 5750
drivers/staging/unisys/visorbus/visorbus_main.o

File size after:
text data bss dec hex filename
14408 7112 832 22352 5750
drivers/staging/unisys/visorbus/visorbus_main.o

This change was made with the help of Coccinelle.
