PCI: Require vendor and device for new_id
Currently, there is no minimum number of fields required when adding a new device ID to a PCI driver through the new_id sysfs file. It is possible to add a new ID with only the vendor ID set, causing the driver to attempt to attach to all PCI devices from that vendor. This has been reported to happen accidentally: http://lists.lm-sensors.org/pipermail/lm-sensors/2007-March/019366.html It is even possible to not even set the vendor ID field, causing the driver to attempt to attach to _all_ the PCI devices. This sounds dangerous and I fail to see any valid use of this "feature". Thus I suggest that we now require at least the first two fields (vendor ID and device ID) to be set. For what it's worth, this is what the USB subsystem does. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
