    Fix pointer/int cast in USB devio code, and thus avoid a compiler warning.
    
    A void* data argument passed to bus_find_device() and thence to match_devt()
    is used to carry a 32-bit datum.  However, casting directly between a u32 and
    a pointer is not permitted - there must be an intermediate cast via (unsigned)
    long.
    
    This was introduced by the following patch:

    	    usbfs: simplify the lookup-by-minor routines
    
    	    This patch (as1105) simplifies the lookup-by-minor-number code in
    	    usbfs.  Instead of passing the minor number to the callback, which
    	    must then reconstruct the entire dev_t value, the patch passes the
    	    dev_t value directly.
