[PATCH] amdgpu: Fix failing boot after support for third vce ring

[Ernst Sjöstrand]

Yes, the  6f0359ff73076483902de0c17f9649bf55651e2a I'm referring to is the
same as
780605db12c52f2c22d4d2cc05ceb7d2a9d55579 (only exists in amd-staging).
So the last of those two commits is the one that causes my problem.

Regards
//Ernst
