Did not notice this in first round, sorry. These seems to be sorted
(there's a comment further up about that) so this should be between
AMD and TI a bit more down.

The list isn't sorted at all. I think the comment just wants to

It is still mostly sorted except where people did not get how. Try

grep PCI_VENDOR_ID_ pci_ids.h

say that you should mention the vendor before the devices.

I think it says that PCI_VENDOR_IDs should be sorted and then DEVICE_IDs within 
them should also be sorted but device IDs intervene VENDOR_IDs so the sorting 
of VENDOR_IDs may not be obvious at first sight.

Anyway, as the list currently is, there are multiple positions
where HP could be added...

Yes, some IDs already break this sorting but we could still avoid breaking it 
more. [...]

... that's why I added "HP" it after "DEC" :-)

But it should be sorted by ID number not name that's why it should be between 
AMD 0x1022 and TI 0x104c.

Oh, I see!
It's sorted by *numeric* PCI ID number.
Will fix in next round or before final pull request.
