This patch updates the round_rate() logic here to return zero instead of a negative number on error.
In conjunction with higher-level changes associated with acting on the return value of clk_ops->round_rate() it is then possible to have clk_ops->round_rate() return values from 1 Hz to ULONG_MAX Hz instead of the current limitation of 1 Hz to LONG_MAX Hz.
