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.
