Note that we've landed snapshotting of the DSC block in [1] because we
need it now, and - as discussed elsewhere - is perfect material to be
submitted in a standalone, appropriately described/titled patch (fine to
be part of a series, as long as that patch comprises this single diff).

Keep in mind that it was added at the bottom of dpu_kms_mdp_snapshot()
instead of the top, so git might not clean it up or mark it as conflict
during a rebase; don't forget to drop it from v2 :)
