    kconfig: reset generated values only if Kconfig and .config agree. · d8982ba1

    Normally generated values (Kconfig entries without a prompt) are cleared as
    they are regenerated anyway and so they appear as new should they become
    visible and defaults work as expected (once a value is set defaults aren't
    used anymore).
    
    The detection whether a value is generated or not is only based on its
    visibility status, which can quickly change for a lot of symbols by just
    removing a single line from .config or adding a dependency to Kconfig as you
    noticed.
    
    The patch now suppresses this logic when .config and Kconfig aren't in sync
    and .config needs to be updated, so that you can remove now a random value
    from .config and oldconfig won't reask for many other values.
