we definitely don't want to cast this to an int.  But what's wrong with

if (device->driver)
	continue;

it reads properly `if device has driver then continue'.  Sure, it's complex
to think about if you try and puzzle it out `so, if i've assigned a value to
driver then it's not 0, so this is true in which case continue', but if you
just read it, it says what it means.
