[PATCH 2/7] PCI: Make pci_wakeup_bus() & pci_bus_set_current_state() public
...owerdown and update the current_state to D3cold. On powerup the PCI device itself and the hierarchy below it is in D0uninitialized, so we need to walk the hierarchy again and wake all devices, causing them to be put into D0active and then letting them autosuspend as they see fit. To this end make pci_wakeup_bus() & pci_bus_set_current_state() public so PCI drivers don't have to reinvent the wheel. Cc: Bjorn Helgaas <bhelgaas at google.com> Cc: Rafael J.
