PCI/PM: Resume device before shutdown Some actions during shutdown need device to be in D0 state, such as MSI shutdown etc, so resume device before shutdown. Without this patch, a device may not be enumerated after a kexec because the corresponding bridge is not in D0, so that configuration space of the device is not accessible.
