In the function netxen_pinit_from_rom there is this code...

	buf = kcalloc(n, sizeof(struct crb_addr_pair), GFP_KERNEL);
	if (buf == NULL) {
		printk("%s: netxen_pinit_from_rom: Unable to calloc memory.\n",
				netxen_nic_driver_name);
		return -ENOMEM;
	}
	for (i = 0; i < n; i++) {
		if (netxen_rom_fast_read(adapter, 8*i + 4*offset, &val) != 0 ||
		netxen_rom_fast_read(adapter, 8*i + 4*offset + 4, &addr) != 0)
			return -EIO;

There should be a kfree of buf before the "return -EIO".
