[PATCH 0/2] PCI: Fix runtime PME generation from D3hot

From: Mika Westerberg

Hi all,

Heiner reported [1] that runtime PME generation of his network card does
not work after commit 0e157e528604 ("PCI/PME: Implement runtime PM
callbacks") that landed in v4.20. Reverting the commit helps but it has
another drawback, which I originally tried to solve with the commit, that
the PCIe hierarchy wakes up immediately after being put into D3cold.

This series of two patches tries to fix both issues so that PME wakes up
from D3hot and that the hierarchy does not wake up immediately from D3cold.
