Subject: drm/amdgpu: use moving fence instead of exclusive for VM updates
X-Git-Tag: v5.5-rc1~128^2~26^2~326

drm/amdgpu: use moving fence instead of exclusive for VM updates

Make VM updates depend on the moving fence instead of the exclusive one.

Makes it less likely to actually have a dependency.
