Sorry, I've no clue what's with that list of PCI SIG member companies.
Of course a company which no longer has a legal status cannot be a
member of the PCI SIG.

FWIW, the lspci tool uses this database: https://pci-ids.ucw.cz/

Because that company doesn't produce new equipment with the old vendor id.

Aliasing the old vendor id to the current company name is polluting the
Linux definitions.

The goal, quite simply, is to call the Freescale PCI ID "Freescale".
