    [PATCH] UHCI: Improve FSBR-off timing · c5e3b741
    Alan Stern authored
    This patch (as707) improves the FSBR operation in uhci-hcd by turning it
    off more quickly when it isn't needed.  FSBR puts a noticeable load on a
    computer's PCI bus, so it should be disabled as soon as possible when it
    isn't in use.  The patch leaves it running for only 10 ms after the last
    URB stops using it, on the theory that this should be long enough for a
    driver to submit another URB if it wants keep FSBR going.
