The patch titled
pci: Introduce pci_find_present
has been added to the -mm tree. Its filename is
pci-introduce-pci_find_present.patch
See http://www.zip.com.au/~akpm/linux/patches/stuff/added-to-mm.txt to find
out what to do about this
------------------------------------------------------
Subject: pci: Introduce pci_find_present
From: Alan Cox <alan@xxxxxxxxxx>
This works like pci_dev_present but instead of returning boolean returns
the matching pci_device_id entry. This makes it much more useful. Code
bloat is basically nil as the old boolean function is rewritten in terms of
the new one.
This will be used by the updated VIA PCI quirks for one
