From: Nicholas Kazlauskas <[email protected]> [Why] For medium updates that change nothing but the source rect position the viewport doesn't change on DCN20.
We're missing the check for the position update bit that was there in the DCN10 hardware sequencer. [How] Check the position bit along with the scaling bit like we were doing with DCN20. We shouldn't actually hit a case where context != current_state in our programming/commit model but guard against it anyway since it was guarded for the other bits.
