[PATCH] net: can: at91_can: constify attribute_group structures.

From: Arvind Yadav
Date: Mon Jul 10 2017 - 04:02:02 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
6164 304 0 6468 1944 drivers/net/can/at91_can.o

File size After adding 'const':
text data bss dec hex filename
6228 240 0 6468 1944 drivers/net/can/at91_can.o
