I think you can just make the revert the first patch in your series and when it
is ready I can pick up only the revert in the driver-core tree; everything else
can go through your pmdomain tree.

I.e. you don't need the revert in your pmdomain tree as it should still have
dev_has_sync_state() exported in device.h.
