bc8f10babcc2 "EDAC, pnd2: Properly toggle hidden state for P2SB PCI device" doesn't apply cleanly without 3e5d2bd19138 "EDAC, pnd2: Build in a minimal sideband driver for Apollo Lake". The backport is not straightforward, and I'm not sure how to validate if I did attempt a backport. Can you please advise if we should also take that commit, or else provide us with a tested backport of bc8f10babcc2 to 4.13? Thanks!
