#	drivers/pci/hotplug.c	1.4     -> 1.5    
#
# The following is the BitKeeper ChangeSet Log
# --------------------------------------------
# 02/09/09	greg@kroah.com	1.626
# PCI: hotplug core cleanup to get pci hotplug working again
# 
# - removed pci_announce_device_to_drivers() prototype as the function is long gone
# - always call /sbin/hotplug when pci devices are added to the system if
#   so configured (this includes during the system bring up.)
