While looking through the irda-usb driver, I found that it does several
questionable things.
irda_urb_net_timeout() looks at urb->status while the URB is
still in progress.
Even worse, it changes urb->status!
The driver uses the urb->timeout field. This field is supported
only by the UHCI driver, and I would like to remove that support.
Right now there are only about 3 drivers that use urb->timeout. My
feeling is that we should either remove timeout support entirely or else
move it to usbcore, where it will work with every HCD. This wouldn't be
such a bad thing to do; in fact we could simply take the code already used
by usb_bulk/control_message() and put it in a more central location. (If
it were available in this way, usb-storage could be simplified.)
