Can someone bounce me a copy of the current udev patch?

Rather than being in the "create/destroy" functions, the refcounting 
should be in the probe/remove functions.  And it also needs to handle 
errors on registration. 

This particular API call was there before 2.6.16, and it is also not 
used by most of the in-kernel USB drivers.  So I'm honestly not sure 
when it's actually of use.

The prism_usb's hardware is rather finiky, to stay the least.. but 
essentially, on a suspend, the hardware goes away but the driver does 
not.  The driver needs to reset itself by basically going into 
ifstate_disable state.  That said, in the case of USB I believe the 
device should be disconnecting itself from the bus, so the driver stack 
should go down and come back up cleanly.

That's the theory, anyway..
