Yea, I saw that. I assume that the places that don't check don't
*need* to check. But maybe this driver is junk and other bugs lurk.
I'm not sure. Either way, I think this change is certainly an
improvement on the status quo. I don't intend to develop further on
it, but feel free to send patches atop once this lands.
