[PATCH] hwmon: adc128d818: constify attribute_group structures.

From: Arvind Yadav
Date: Wed Jul 05 2017 - 01:22:45 EST


attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups 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
2304 2936 0 5240 1478 drivers/hwmon/adc128d818.o

File size After adding 'const':
text data bss dec hex filename
2344 2872 0 5216 1460 drivers/hwmon/adc128d818.o
