The previous version of the get_rate helper does not work if the mux clock parent is changed after the probe. This error has not been detected because this condition has not been tested. The error occurs because the set_parent helper does not change the parent of the clock device but only the clock selection register. Since changing the parent of a probed device can be tricky, the new version of the get_rate helper provides the rate of the selected clock and not that of the parent.
