It updates the "ohci-hcd" driver to address two issues, one            
of which could potentially have caused oopses.  First, it takes
out calls to usb_dec_dev_use() on the submit error path; that's
already done elsewhere.  (Noted by Georg Acher.)  Second,
it removes some pointless diagnostics.  One is for schedule
overrun interrupts, the other is for accessing the frame counter.
