Hi Krzysztof,

Thanks very much for your quickly review.

I think it is ok if it go through memory tree. In the original patch, we
pm_runtime_get(smi-common-dev) in the smi-larb's pm resume callback.
This patch only use device-link do this. thus, this patch have no
function change. it only adjusts the SMI internal code flow.

In addition, [14/16] expects your Acked-by. and that one should be
merged with the others.

About the others patches, I'm not sure which tree they should go
through. they cross several trees, dt-binding/iommu/media/drm/dts.

Not sure if Matthias could have time to review and give some suggestion.
