[PATCH] input: synaptics-rmi4: constify attribute_group structures.

From: Arvind Yadav
Date: Wed Jul 05 2017 - 06:24:33 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
5287 448 0 5735 1667 drivers/input/rmi4/rmi_f34.o

File size After adding 'const':
text data bss dec hex filename
5339 384 0 5723 165b drivers/input/rmi4/rmi_f34.o
