opp: Change return type of devm_pm_opp_register_set_opp_helper()
Make devm_pm_opp_register_set_opp_helper() to return error code instead of opp_table pointer in order to have return type consistent with the other resource-managed OPP helpers. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>
