Subject: BUG null dereference in driver ./drivers/isdn/icn/icn.c

	KERNEL_VERSION: 2.6.32
	SUBJECT: null dereference after check
	DESCRIBE:
	In driver ./drivers/isdn/icn/icn.c in function icn_addcard:

1. If in line 1580 card2 = NULL  then we goto line 1581
2. In line 1581 we have null dereference because printk called with card2-
>interface.id in third parameter.

1580        if (!(card2 = icn_initcard(port, id2))) {
1581                printk(KERN_INFO
1582                       "icn: (%s) half ICN-4B, port 0x%x added\n",
1583                       card2->interface.id, port);
1584                return 0;
1585        }
