It would make it easier to read and safer to type if you used a macro
to generate the fields.

#define PCITBL(v,d,sv,sd) \
 { PCI_VENDOR_ID_##v, PCI_DEVICE_ID_##d, \
   PCI_VENDOR_ID_##sv, PCI_DEVICE_ID_##sd }

#define PCITBL_END {0,0,0,0}

static struct pci_device_id foo_pci_tbl[] __initdata = {
  PCITBL(INTEL, INTEL_82437VX, ANY, ANY),
  PCITBL_END
}

Shorter is easier to read.  Using a prefix on the fields makes it much
harder for somebody to accidentally swap device and vendor codes.  If
they swap the parameters and type
  PCITBL(INTEL_82437VX, INTEL, ANY, ANY),
by mistake then they get compile errors, PCI_VENDOR_ID_INTEL_82437VX
and PCI_DEVICE_ID_INTEL are undefined.
