    Subject[RFC PATCH 2/3] usb, PCI: remove disable/enable device with non-xhci quirk
    Date
    | commit cab928ee1f221c9cc48d6615070fefe2e444384a
    | USB: Fix handoff when BIOS disables host PCI device.

    mention only need to do disable/enable for xhci controller.

    So just remove that for non-xhci controller and restore old behavior for them.
