Yes, it seems so. Many thanks to Jerry for this fix.
I've tested it with latest amd-staging-drm-next #4ce527eb8bb3 on my 
Polaris 20. Both cases (kdm_greet and 'screen blank') are solved. W'll 
apply it on drm-next-4.15-dc, too.

Side note:
HDMI audio is _gone_ after logout and relogin.
Missing reinitialization?

Next:
Fix fan speed...

Thank you very much!
Dieter
