Indeed, just disabling the FIXUP implemented by that commit fixes
suspend for me, with 4.10.0-rc3. Btw, this is on a Thinkpad x201s.
(For the addressees newly added to cc, it seems like the mentioned
commit breaks suspend to ram on Dell XPS13 and Thinkpad x201s)

I don't know what this may break, as the description of 7279b23 just
says:
"This workaround was added to support other broken OS and we need to
follow here."
Unless there is a better justification, I think the commit should be
reverted, for now.
