Quoting from my cover letter:

"After this series there still is a concern regarding the possible increase of
power draw that may result from the processing of non-wakeup EC events while
suspended which is why the change only affects Dell XPS13 9360 and 9365
for now."

So that is what happens, unfortunately, and we can't do much about it
at the moment.

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.

The only way to avoid that would be to reconfigure the EC during
suspend to stop generating non-wakeup events, but today we have no
reliable way to do that.

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?
