The actual code is all obviously out of tree, I'd expect any Android BSP
to contain at least some usage of it (though often just the basic GPIO
one for CPU vendor ones).

I'd not characterise it as a massive problem (and wakelocks won't hold
back anything that doesn't have other problems). I suspect that the
code for a Samsung phone with the 30 pin connector will show something
interesting, though I can't say I've actually looked. For things like
headset detection there's already ways to support things in mainline and
we should just end up hooking extcon into the central support for these
things.
