Pull power management fixes from Rafael Wysocki:
"These fix two bugs in error code paths in the cpufreq core and in the
kirkwood-cpufreq driver.
Specifics:
- Make cpufreq_register_driver() return an error if the ->init()
calls fail for all CPUs to prevent non-functional drivers from
hanging around for no reason (David Arcari).
- Make kirkwood-cpufreq check the return value of
clk_prepare_enable() (which may fail) as appropriate (Arvind
Yadav)"
