It's OK for the devices the\ndriver itself creates at the module probe time, but if the device is\nbound manually via sysfs interface, this could be -1 as \"none\", and\nthis leads to OOB access for index[] and other parameters.\n\nAdd a sanity check for the card index and warn/correct it if it's a\nvalue out of the range.",
