Those were found while working on simple-dmabuf-v4l, as found in the
next patch of this series.
After each buffer’s params were ready to be submitted to the
compositor, a roundtrip was done, which is wasteful since we can do it
only once after having queued all the params we want. Removing those
nested roundtrips also prevent the potentially dangerous side-effect of
calling callbacks for later events while previous events were still
being processed.
An extraneous surface damage was also removed.
