You are right, but if anything I'd squash the following four driver
patches into this one.  I left the series in little steps just to make
review easier.  Strictly speaking, if you were to do a git bisect from
the introduction of the "2" ioctls until here, you would find drivers'
acceptance of the new flags changing.  But it is too late to fix that,
and I doubt anyone will care.

IMHO it *is* important to have v5.4 with strict checking.
