OK, but at the moment this is a regression in functionality on those
platforms. Without this patchset, I can successfully s2idle
suspend/resume on an XPS 9365 (albeit with a little bit of awkward
fiddling of the power button to resume). After the patchset, I can't
realistically go into s2idle at all.

I thought I had read one one of the threads that this was possible in
the same way that it is for Windows on these laptops.  What's missing
to make this possible?
