If I'm not mistaken, the driver just broke now and will not bind
properly to this device, right?
Ick, oh well, I'll plod on and hope that you fix this issue up in a
later patch, but note that this might make 'git bisect' cause problems
if someone lands in the middle of this series with things broken
(run-time, not build time).
Sorry, I should have caught that first time through this series, I
didn't realize it until right now when I tried it.
