The dev_pm_opp_set_rate() already contains a call for clk_round_rate for the passed value. Stop calling it manually from _dpu_core_perf_get_core_clk_rate(). It is slightly incorrect to call it this way, as we should round the final calculated clock rate rather than rounding all the intermediate values.
