When defining variables and assigning values can be done at the same time.

For future reference: add the name of the driver to the prefix. Saying
'media/pci:' suggests that you patch multiple PCI drivers in that directory.
But 'media/pci/pt1:' indicates that you patch only the pt1 driver.

I've updated the subject, so no need to repost, but remember this for next
time :-)

Regards,

	Hans
