The media tree (or at least venus) moves quite slugglishly..

But looks like applying just the DT patches (which I expect to get
in first) results in a non-platform-killing:

[   25.851120] qcom-venus aa00000.video-codec: Adding to iommu group 11
[   25.851618] qcom-venus aa00000.video-codec: non legacy binding
[   25.916562] qcom-venus aa00000.video-codec: invalid setting for UC_REGION
[   25.916569] qcom-venus aa00000.video-codec: failed to reset venus core
[   25.919000] qcom-venus: probe of aa00000.video-codec failed with error -22

So it should be okay either way.
