I'm currently trying _really_ hard to just drop the whole
/sys/class/usb_host/ stuff entirely as no one currently uses it other
than for debugging stuff.
So I'd really prefer to not add new stuff here that I'll just have to
rip out in a few weeks anyway.
Is there any where else you can add this? Does this really need to be
on a per-host-controller basis? If so, just add it to the host
controller device itself, not in this class_device.
thanks,
greg k-h
