            Bug ID: 107817
           Summary: NV50 : Nvidia NVS295 - Printing out EDID errors about
                    not connected monitor ports
           Product: xorg
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: minor
          Priority: medium
         Component: Driver/nouveau
          Assignee: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
          Reporter: cezdhzez-GK+4nHxFadIswetKESUqMA@public.gmane.org
        QA Contact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org

Card: Nvidia NVS295 with 2 DisplayPort connectors.

Problem: nouveau is spamming the kernel message, that it cant find the EDID of
not connected ports. Of course it cant, because there is no monitor connected
to that port.

When i connect the monitor to DisplayPort number 1, it writes, that it cant
find EDID on DisplayPort number 2. When i connect it to DisplayPort 2, it
writes that it cant find EDID of Display Port 1.

Linux kernel version: Kernel 4.19RC2 (its also there on older kernels)

Output when connected to DisplayPort 2 on kernel 4.19RC2 :

Ben -- probably worth backporting...
