From: Domen Puncer <domen@coderock.org>
As requested by Christoph Hellwig I created a new macro called
for_each_pci_dev. It is a wrapper for this common use of
pci_get/find_device:
(while ((dev = pci_get_device(PCI_ANY_ID, PCI_ANY_ID, dev)) != NULL))
This macro will return the pci_dev *for all pci devices. Here is the first
patch I used to test this macro with. Compiled and booted on my T23.
There will be 53 more patches using this new macro.
