    Much simpler to just pass a "commit" flag and not
    try to come up with some generic way to represent
    "hardware programming information"; in general that
    will be very different between clocks.

    Then clk_round_rate() passes "false" for commit,
    while clk_set_rate() passes "true". And in both
    cases the value returned is the rate, or negative
    errno to indicate a fault.
