Suspend broken on Thinkpad x201s since 4.7-rc1

when trying out 4.7-rc1 on my Thinkpad x201s, I noticed that suspending
the system doesn't work any more. Instead, when trying to suspend,
the system hangs with a black screen and the suspend-LED blinking.

I bisected the issue to commit 22e2f9fa63b092923873fc8a52955151f4d83274,
and indeed, reverting this commit from 4.7-rc1 fixes the issue.

As the system just hangs on suspend, I don't have any error message to
quote. But if there is something I could try to get some diagnostics,
please let me know.
