We can proceed just like video devices: only modify the void input
driver into saying it doesn't need a VT, and the core then avoids
allocating a VT only if *only* the dummy video driver and void input
driver are used.

I'm surprised that the discussion ends up with this way of thinking:
shouldn't it be the converse, i.e. a VT is always allocated *except* if
that is explicitly asked for by a special configuration? Otherwise we'll
keep having users saying that their special use does not trigger a VT
allocation...
