We're at -rc3 now and I haven't seen any promising progress in the last
week. All the while suspend/resume is now broken on at least one board
and that may end up hiding any other issues that could creep in in the
meantime.

Furthermore we seem to have a preexisting issue that may very well
interfere with this patch, so I think the cautious thing is to revert
for now and then fix the original issue first. We can always come back
to this once everything is back to normal.

Also, people are now looking at backporting this to v5.6. Unless we
revert this from v5.7 it may get picked up for backports to other
kernels and then I have to notify stable kernel maintainers that they
shouldn't and they have to back things out again. That's going to cause
a lot of wasted time for a lot of people.

So, sorry, I disagree. I don't think we have "plenty of time".
