[PATCH] net: cdc_ncm: constify attribute_group structures.

From: Arvind Yadav
Date: Mon Jul 10 2017 - 03:56:19 EST


attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/netdevice.h> work
with const attribute_group. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
13275 928 1 14204 377c drivers/net/usb/cdc_ncm.o

File size After adding 'const':
text data bss dec hex filename
13339 864 1 14204 377c drivers/net/usb/cdc_ncm.o
