Log Message:
drm: New mechanism to suspend ioctls during system suspend.
drm drivers must opt into this by calling drm_suspend_ioctl in their
driver suspend routine, and drm_resume_ioctl in their driver resume
routine.
This is a stop-gap measure -- it would be better to fill in the
pm_runtime_* API with new pmf(9) hooks to acquire/release references
to devices for coordinating with suspend/resume, but getting the
details right is tricky, and this stop-gap is enough to get i915
suspend/resume to work reliably on my Kaby Lake laptop. Rather than
wait until I've got all the details right, let's just go with this
stop-gap for now.
