Thanks for the link.  There are 126 comments on that bugzilla so far,
so it'd be nice to have a more specific pointer.  I'm guessing 117
might be the relevant one, so:

Since these constants are only used in one place, don't add them to
pci_ids.h (see comment at the top of this file).  Just use the hex
constants directly in the quirk and include the vendor/device names in
the comment.

Aside from the style issues you've already commented on, I'll give a
thumbs up to quirking this device.  Thanks,

Alex
