[PATCH 2.6.20-rc5] intel_rng: substitue magic PCI IDs with macros

["Ahmed S. Darwish" <darwish.07@gmail.com>]

Substitue intel_rng magic PCI IDs values used in the IDs table
with the macros defined in pci_ids.h

I've used a small script to generate this patch then manually tried to 
make sure it's (hopefully) correct. 

#!/bin/bash

INTEL_RNG_FILE=drivers/char/hw_random/intel-rng.c
TMP_FILE=$(mktemp)
MAGIC_NUMS_FILE=$(mktemp)

# grep the contents of "pci_device_id pci_tbl[]"
grep "{ 0x8086"  drivers/char/hw_random/intel-rng.c > $TMP_FILE
# Extract the magic numbers to be replaced
cat $TMP_FILE | awk ' { print $3 } ' | cut -d, -f1 | grep "0x" > $MAGIC_NUMS_FILE

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

# For each magic number in MAGIC_NUMS_FILE, find its defined macro 
# in pci_ids.h then replace them.

for i in $(cat $MAGIC_NUMS_FILE); do 
    var=$(grep "PCI_DEVICE_ID" include/linux/pci_ids.h | grep "$i" | awk ' { print $2 } ')
    if [[ -n "$var" ]] ; then
	# sed: Side effect of replacing the magic number in the whole file
	# Collisions with other magics belonging to another family ?
	# Manual checking reveals no bad collisions happen.
	sed -i "s/${i}/${var}/g" $INTEL_RNG_FILE
    fi
done

rm -f $TMP_FILE
rm -f $MAGIC_NUMS_FILE
