PM / OPP: rename functions to dev_pm_opp*
Since Operating Performance Points (OPP) functions are specific to device specific power management, be specific and rename opp_* accessors in OPP library with dev_pm_opp_* equivalent. Affected functions are: opp_get_voltage opp_get_freq opp_get_opp_count opp_find_freq_exact opp_find_freq_floor opp_find_freq_ceil opp_add opp_enable opp_disable opp_get_notifier opp_init_cpufreq_table opp_free_cpufreq_table Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Nishanth Menon <nm@ti.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
