From scottm@somanetworks.com Mon May 9 14:58:52 2005 Date: Mon, 9 May 2005 17:36:27 -0400 (EDT) From: Scott Murray To: Greg KH Cc: pcihpd-discuss Subject: PCI Hotplug: remove pci_visit_dev Message-ID: If my CPCI hotplug update patch is applied, then there are no longer any in tree users of the pci_visit_dev API, and it and its related code can be removed.
