    It depends. When CONFIG_USB_HID auto-selected CONFIG_INPUT, did the user
    know about it? Or did it just happen automagically behind the scenes? If
    it was turned on silently, and the subsequent de-select of
    CONFIG_USB_HID silently left CONFIG_INPUT turned on, I'd say that
    violates least-surprise.

    On the other hand, if turning on CONFIG_USB_HID then prompts "to do
    that, I also have to turn on CONFIG_INPUT", i suppose it's ok to leave
    CONFIG_INPUT turned on later.
