The AMD/ATI Oland [1002:6611]'s HDMI output status is not synchronous as shown on UI after hot re-plug the HDMI cable, if it is radeon in used. The amdgpu module does not hit this issue.

This patch disables [1002:6611] in radeon and enables it in amdgpu.

Fixes: https://gitlab.freedesktop.org/drm/amd/-/issues/1117 Signed-off-by: Jian-Hong Pan jian-hong@endlessm.com

Nack. Amdgpu does not have support for VCE or UVD yet so you are just trading one issue for another. It would be better to figure out why the audio is not updated properly in some cases.
