  Battery drains when laptop is off  (shutdown)

Bug description:
  == SRU Justification ==
  A regression was introduced in 4.13-rc1 and newer kernels.  This
  regression caused battery drain during system suspend, hibernation or
  shutdown for some PCI devices that are not allowed by user space to wake
  up the system from sleep (or power off).

  This fix has been submitted upstream and cc'd to stable.  However, it
  has not landed in linux-next or mainline yet, so it is being sent as
  SAUCE.

  == Fix ==
  UBUNTU: SAUCE: PCI / PM: Check device_may_wakeup() in pci_enable_wake()

  == Regression Potential ==
  Medium.  Commit fixes a current regresssion, but affects PCI power management.
  It will also be submitted to upstream stable and have additional review.
  The commit is a clean cherry pick, builds successfully and was confirmed
  to resolve regression.

  == Test Case ==
  A test kernel was built with this patch and tested by the original bug 
reporter.
  The bug reporter states the test kernel resolved the bug.


  == Original Bug Description ==
