In commit 5c5992cb90cf ("clk: Add debugging for return values"), a temporary storage variable was added around the ops->get_rate() call inside clk_get_rate(), so that the result could be passed through log_ret.
This temporary variable was declared as an int, yet when we look in struct clk_ops, we can see this needs to be a ulong: ulong (*get_rate)(struct clk *clk);
This was resulting in a signed to unsigned casting error on our builds, where a clock value of 0xABCDABCD was being incorrectly cast to 0xFFFFFFFFABCDABCD.
