gpio-exar: Why filtering out Commtech devices?

Hi Sudip,
why do we carry
if (pcidev->vendor != PCI_VENDOR_ID_EXAR)
return -ENODEV;
in gpio_exar_probe? This effectively prevents that
EXAR_DEVICE(COMMTECH, COMMTECH_4222PCIE, pbn_exar_XR17V35x),
EXAR_DEVICE(COMMTECH, COMMTECH_4224PCIE, pbn_exar_XR17V35x),
EXAR_DEVICE(COMMTECH, COMMTECH_4228PCIE, pbn_exar_XR17V35x),
gain GPIO support. Do those devices lack access to the pins? Or can we
drop the filter. I don't have access to those devices, just wondering
because the code is not explaining the reason.
