drivers/net/at1700.c: at1700_probe1: array overflow

[Adrian Bunk <bunk@stusta.de>]

The Coverity checker found the following:

<--  snip  -->

...
static int at1700_ioaddr_pattern[] __initdata = {
        0x00, 0x04, 0x01, 0x05, 0x02, 0x06, 0x03, 0x07
};
...
static int __init at1700_probe1(struct net_device *dev, int ioaddr)
{
...
	for (l_i = 0; l_i < 0x09; l_i++)
		if (( pos3 & 0x07) == at1700_ioaddr_pattern[l_i])
			break;
	ioaddr = at1700_mca_probe_list[l_i];
...
}
...

<--  snip  -->


This can result in indexing in an array with 8 entries the 10th entry.

        of the darkness. There had been need of rain for many days.
       "Only a promise," Lao Er said.
