Rather than repeating this test, you should do it once at probe time, and set a "new interface" single-bit flag in some hptiop_hba field.

Less maintenance intensive, less prone to error, and removes expensive tests from the driver hotpath.


static struct pci_device_id hptiop_id_table[] = {
- { PCI_DEVICE(0x1103, 0x3220) },
- { PCI_DEVICE(0x1103, 0x3320) },
+ { PCI_DEVICE(PCI_VENDOR_ID_TTI, 0x3220) },
+ { PCI_DEVICE(PCI_VENDOR_ID_TTI, 0x3320) },
+ { PCI_DEVICE(PCI_VENDOR_ID_TTI, 0x3520) },
+ { PCI_DEVICE(PCI_VENDOR_ID_TTI, 0x4320) },
{},

Using the PCI_VDEVICE() macro can make this even shorter:

{ PCI_VDEVICE(TTI, 0x4320) }
