Heh, but it's obvious when you read the commend in the entry :)

(Though, this is a drawback of using PCI_* definition.  The definition
 isn't always unique, so a simple grep isn't possible to search for
 a device with 1102:8938.  So, I'm not 100% fan of such a conversion
 although I agree that this improves readability much.)

Anyway, could you change that entry and repost?  Nno need to repost
all in the series, of course :)


thanks,

Takashi
