    USB: Remove the SAW_IRQ hcd flag · 968b822c
    Alan Stern 提交于
    The HCD_FLAG_SAW_IRQ flag was introduced in order to catch IRQ routing
    errors: If an URB was unlinked and the host controller hadn't gotten
    any IRQs, it seemed likely that the IRQs were directed to the wrong
    vector.
    
    This warning hasn't come up in many years, as far as I know; interrupt
    routing now seems to be well under control.  Therefore there's no
    reason to keep the flag around any more.  This patch (as1495) finally
    removes it.
