After following recent cleanups by Bjorn: http://git.kernel.org/cgit/linux/kernel/git/helgaas/pci.git/log/?h=pci/hotplug 2cc56f3 PCI: pciehp: Remove assumptions about which commands cause 40b9608 PCI: pciehp: Compute timeout from hotplug command start time 3461a06 PCI: pciehp: Wait for hotplug command completion lazily 4283c70 PCI: pciehp: Make pcie_wait_cmd() self-contained the bitfield no_cmd_complete is not really needed anymore, as there is only a single occurance of its use. Hence remove the unnecessary bit field, and use existing macro NO_CMD_CMPL() instead.
