Well, here:

https://bugzilla.kernel.org/show_bug.cgi?id=190861#c26

you said:

"Shutdown and suspend/resume work on 4.7.0-1 but fail on 4.8. and 4.9."

and here:

https://bugzilla.kernel.org/show_bug.cgi?id=190861#c29

you said:

"the pci_port_pm=off
fixes both the firefox issue and the lock screen issue. Also suspend/resume work.
Tested on 4.9"

which to me means that suspend/resume is also broken for you
due to the PCIe ports PM support enabled (the command line option
should be pcie_port_pm=off, BTW, but I'm assuming that this is what you
actually used).

Now, it may be broken due to the runtime PM breakage triggering after system
resume (which may be verified by checking if the revert actually fixes system
suspend-resume too on your machine), but even then I wouldn't revert that
particular commit.

Thanks,
Rafael
