In fact, I don't think there is much problem keeping the pci_dev
structure around if it has been unlinked from the bus & other kobject
hierarchy, but make sure of that ... It will ultimately go away though.

"nasty habit" ... I there anything in linux you won't qualify of "nasty
habits" one day ? :) I hate braces for one lines. they are ugly.

You should always do a dirdiff pass to review your patches, that catches
these things, and sometimes others...

Get the linux kernel coding style changed ? wow ! good luck :) You won't
win a battle whose entire point it to create uglyness ;)

Then attach your structures to the device-tree instead. No need to
duplicate the structure.
