    [PATCH] UHCI: remove main list of URBs · 0ed8fee1
    Alan Stern authored
    As part of reorienting uhci-hcd away from URBs and toward endpoint
    queues, this patch (as625) eliminates the driver's main list of URBs.
    The list wsa used mainly in checking for URB completions; now the driver
    goes through the list of active endpoints and checks the members of the
    queues.
    
    As a side effect, I had to remove the code that looks for FSBR timeouts.
    For now, FSBR will remain on so long as any URBs on a full-speed control
    or bulk queue request it, even if the queue isn't advancing.  A later
    patch can add more intelligent handling.  This isn't a huge drawback;
    it's pretty rare for an URB to get stuck for more than a fraction of a
    second.  (And it will help the people trying to use those insane HP USB
    devices.)
