Not that this error seems to have anything to do with me, but I did a
quick grep and my best guess is that the error you're seeing is
related to this patch:

    drm/amd/display: Use HDMI FreeSync range from common EDID parser

    HDMI FreeSync on amdgpu is detected using the AMD VSDB parser in the
    DMUB firmware, now that the common DRM EDID parser can do the same, use
    the common parser.

    Extend get_amd_vsdb() to copy the relevant flags and data now being
    extracted from the AMD VSDB. Additionally, parse_hdmi_amd_vsdb() and the
    parse_edid_cea() firmware helpers now have no callers; remove them.

    (Adjust for movement to amdgpu_dm_connector.c)

That seems to have removed the parse_hdmi_amd_vsdb(). Despite the
commit message, the function prototype is still in a header and there
are still callers to it in amdgpu_dm_connector_test.c.

Adding the two people involved in that patch to this email thread.

Seems like the kernel test robot could use some help identifying the
proper patch / people involved.
