Since this variable has users outside of this file and uses the extern keyword to change its visibility, move the variable declaration to the header file. This resolves the following sparse warning: drivers/pci/hotplug/cpci_hotplug_core.c:47:5: warning: symbol 'cpci_debug' was not declared. Should it be static?
