Hi all, Here's the updated patch. 

Substitue magic values used in the PCI IDs table with macros defined in 
pci_ids.h + using the PCI_DEVICE macro.

I've used a script to generate that patch, then checked the results manually
to make sure that it's (hopefully) correct.

#!/bin/bash

INTEL_RNG_FILE=drivers/char/hw_random/intel-rng.c
TMP_FILE=$(mktemp)
# File to hold Magic PCI deviceIDs in the "pci_device_id pci_tbl[]"
MAGIC_DEVICE_IDS=$(mktemp)

# All pci_tbl[] contents begin with a "{ 0x8086"
grep "{ 0x8086"  drivers/char/hw_random/intel-rng.c > $TMP_FILE
awk ' { print $3 } ' $TMP_FILE | cut -d, -f1 | grep "0x" > $MAGIC_DEVICE_IDS

sed -i "s/{ 0x8086/{ PCI_VENDOR_ID_INTEL/g" $INTEL_RNG_FILE

# For each magic number in MAGIC_DEVICE_IDS, find its defined macro 
# in pci_ids.h then use it in the PCI IDs table.

for i in $(cat $MAGIC_DEVICE_IDS); do 
    macro=$(grep "PCI_DEVICE_ID" include/linux/pci_ids.h | grep "$i" | awk ' { print $2 } ')
    if [[ -n "$macro" ]] ; then
	sed -i "s/{ PCI_VENDOR_ID_INTEL, ${i},.*}/{ PCI_DEVICE(PCI_VENDOR_ID_INTEL, ${macro}) }/" \
	    $INTEL_RNG_FILE
    else
	sed -i "s/{ PCI_VENDOR_ID_INTEL, ${i},.*}/{ PCI_DEVICE(PCI_VENDOR_ID_INTEL, ${i}) }/" \
	    $INTEL_RNG_FILE
    fi
done

rm -f $TMP_FILE
rm -f $MAGIC_DEVICE_IDS
