[amd-staging-drm-next] broken after Navi merge

[Dieter Nützel]

Hello Alex,

after your latest Navi merge 'amd-staging-drm-next' is broken with 
Polaris 20.

It hangs with very light gray (mostly black) screen after first mode 
switch.

Tested commit:
317d5033ab6c (HEAD -> amd-staging-drm-next, origin/amd-staging-drm-next) 
drm/amdgpu: add job->preamble_status back to status value

Even run mode 3|1 with grub2 do not works.

I have to roll back before Navi commits to get working 
'amd-staging-drm-next' kernel, again.

Maybe you have some 'spare' time despite all your Navi enablement work 
to lift 'amd-staging-drm-next' to at least 5.2-rc6 (the Steam TCP 
thing).

Greetings,
Dieter
