I will do that this week (and also add this control to v4l2-common.c). BTW,
in the future changesets that modify or add to the v4l2 spec should only be
accepted if it also includes an update for the v4l2 spec. Now that the spec
is part of the repository there is no excuse for not updating it.
This change predates the merging of the spec, so it's not a problem here.

Hans
