This is how DRM does it...
for (i = 0; driver->pci_driver.id_table[i].vendor != 0; i++) { pid = (struct pci_device_id *)&driver->pci_driver.id_table[i];
pdev = NULL; /* pass back in pdev to account for multiple identical cards */ while ((pdev = pci_get_subsys(pid->vendor, pid->device, pid->subvendor, pid->subdevice, pdev)) != NULL) { /* stealth mode requires a manual probe */ pci_dev_get(pdev); drm_get_dev(pdev, pid, driver); } } return 0;
