    USB: EHCI: remove unused Link Power Management code · 4968f951
    Alan Stern authored
    This patch (as1622) removes the USB-2.1 Link Power Management code
    from the ehci-hcd driver.  This code was never integrated with
    usbcore, it is full of bugs, and it was not getting used by anybody.
    
    However, the debugging code for dumping the LPM-related fields in the
    EHCI registers is left in place.  In theory it might be useful to see
    these values, even though we don't use them.
    
    This essentially amounts to a partial revert of commit
    aa4d8342 (USB: EHCI: EHCI 1.1
    addendum: preparation) and an almost full revert of commit
    48f24970 (USB: EHCI: EHCI 1.1
    addendum: Basic LPM feature support) plus its follow-ons.
