Title:
  System hangs after play video from thunderbolt HDD and then S3

Status in linux-oem package in Ubuntu:
  Invalid
Status in linux-oem source package in Bionic:
  Fix Released

Bug description:
  [Impact]
  System hangs after played video from TBT storage, and then suspend the 
system. It enters suspend correctly, but hangs during waking up.

  [Fix]
  There are 2 commits in upstream which fix this issue.
     95c80bc6952b PCI/PME: Fix hotplug/sysfs remove deadlock in 
pcie_pme_remove()
     3943af9d01e9 PCI: pciehp: Ignore Link State Changes after powering off a 
slot

  [Test]
  Verified on below thunderbolt interface with thunderbolt HDD
  01:00.0 PCI bridge [0604]: Intel Corporation JHL6340 Thunderbolt 3 Bridge (C 
step) [Alpine Ridge 2C 2016] [8086:15da] (rev 02)

  [Regression Potential]
  Low, both commits have been SRU to Ubuntu Disco 5.0 kernel through stable 
update, and the fix on remove functions are small and reasonable.
