Hm I see, not sure if this is the right place to talk about the code,
but is there a reason for the fixup table to be the same for PCI and
Codec SSIDs? (I know it's not like it could be separated at this point).
Also, is there a reason to match by PCI before Codec? A few ideas I
thought:

1. Just check if the PCI and Codec SSID match the exact SSIDs of this device 
(not elegant)
2. For every lookup, check with both
