Subject: pci: Stamp out pci_find_* usage in fakephp
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=094ed76e8988d46158b036ab150e0c22aff6db3a;p=linux-beck.git

pci: Stamp out pci_find_* usage in fakephp

pci_find is not hotplug safe, so it really doesn't want to be in an
actual hotplug driver either.
