[PATCH 0/3] MR6915: Correctly return failures for dmo_wrapper_sink_Receive().
This MR fix some video play crashes for KiriKiri games. If we don't correctly return failure in dmo_wrapper_sink_Receive() call, the worker thread which calls Receive() will continue running and crashes then. With this MR, the worker thread will terminate as expected because Receive() fails. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/6915
