    regulator: Fix 'do-nothing' value for regulators without suspend state · 3edd79cf
    Marek Szyprowski authored
    Some regulators don't have all states defined and in such cases regulator
    core should not assume anything. However in current implementation
    of of_get_regulation_constraints() DO_NOTHING_IN_SUSPEND enable value was
    set only for regulators which had suspend node defined, otherwise the
    default 0 value was used, what means DISABLE_IN_SUSPEND. This lead to
    broken system suspend/resume on boards, which had simple regulator
    constraints definition (without suspend state nodes).
    
    To avoid further mismatches between the default and uninitialized values
    of the suspend enabled/disabled states, change the values of the them,
    so default '0' means DO_NOTHING_IN_SUSPEND.
