However, we share pci ids between projects as:
/*
* A pci_device_id struct {
* __u32 vendor, device;
* __u32 subvendor, subdevice;
* __u32 class, class_mask;
* kernel_ulong_t driver_data;
* };
* Don't use C99 here because "class" is reserved and we want to
* give userspace flexibility.
*/
so iterating over a table is a lot more amenable to plugging in the
common chipset identifiers.
