            Bug ID: 221918
           Summary: amdgpu - Cannot find any crtc or sizes on AMD card
                    with no crtc by design :-)
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Video(DRI - non Intel)
          Assignee: [email protected]
          Reporter: [email protected]
        Regression: No

Getting a loop of "[drm] Cannot find any crtc or sizes" on an AMD Card with no
CRTC's by design (AMD Radeon Pro V620)

Since this is a compute-only GPU, the looping "[drm] Cannot find any crtc or
sizes" really isn't helpful and keeps the card in an incomplete state.

Kernel: 7.1.6-1-cachyos
Architecture: x86_64
