Is this code path checking Disk hibernation aka freeze() / raw()? If this this
just spend to RAM, then this might explain why this fails for me.

As noted on IRC 4.10-rc2 w/ drm-next-4.10-wip and 4.10-rc3 w/ drm-next-4.11-wip
do not require this commit to be reverted.

Hibernate (freeze), Resume (thaw) seem to work fine here, keeping ticket open
for further testing.
