Well, since the patch should not change the behaviour
of the drivers, it probably doesn't matter to users
either way. However, it touches a number of places,
which can break patches that others are working on,
so maybe you should get it upstream at a point that
has the least impact to developer (possibly now).

Doing it now at least makes it easier to test
moving drivers to unlocked operation.
