drm/amdgpu/display: fix aux registration (v2)
We were registering the aux device in the MST late_register rather than the regular one. v2: handle eDP as well Fixes: 405a1f9090d1ac ("drm/amdgpu/display: split dp connector registration (v4)") Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1100 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Reviewed-by: Harry Wentland <harry.wentland@amd.com>
