    USB: flush outstanding URBs when suspending · 6840d255
    Alan Stern authored
    This patch (as989) makes usbcore flush all outstanding URBs for each
    device as the device is suspended.  This will be true even when
    CONFIG_USB_SUSPEND is not enabled.
    In addition, an extra can_submit flag is added to the usb_device
    structure.  That flag will be turned off whenever a suspend request
    has been received for the device, even if the device isn't actually
    suspended because CONFIG_USB_SUSPEND isn't set.
    It's no longer necessary to check for the device state being equal to
    USB_STATE_SUSPENDED during URB submission; that check can be replaced
    by a check of the can_submit flag.  This also permits us to remove
    some questionable references to the deprecated power.power_state field.
