I am actively working on killing the remaining users of
pci_find_device(). The results can be found in the 'isdn-pci' and
'warnings' branches of jgarzik/misc-2.6.git. Time consuming work
converting ancient drivers to PCI hotplug API, but it's almost done.
HOWEVER, given the limited number of drivers that are turned off when
that API is disabled, I felt it would be nice to provide the option
of eliminating the pci_find_* warnings that emit on every build (due
to presence in drivers/pci/search.c).
Please consider pulling from 'pci-legacy' branch of
master.kernel.org:/pub/scm/linux/kernel/git/jgarzik/misc-2.6.git pci-legacy
to receive the following updates:
