The idea was to write "1" to the register if the value of rate is
anything else than 125000000.
To make it easier to read, I will change this to below:
    - iowrite32(rate != 125000000, mgmt->reg);
    + if (rate != 125000000)
    +     iowrite32(1, mgmt->reg);
    + else
    +     iowrite32(0, mgmt->reg);

Hope that's fine. Thanks for your comment
