From alan@lxorguk.ukuu.org.uk Fri Sep 29 10:11:06 2006 Subject: [PATCH] pci: Stamp out pci_find_* usage in fakephp From: Alan Cox To: greg@kroah.com Date: Fri, 29 Sep 2006 18:36:15 +0100 Message-Id: <1159551376.13029.51.camel@localhost.localdomain> pci_find is not hotplug safe, so it really doesn't want to be in an actual hotplug driver either.
