Power management fixes for v4.10-rc1 - Prevent the acpi-cpufreq driver from crashing on exit by fixing a check against the __cpuhp_setup_state() return value and fix the kerneldoc description of that function to make it clear that it may return positive numbers on success too (Boris Ostrovsky). - Drop an incorrect __init annotation of a function in the s3c64xx cpufreq driver and fix a build warning generated (by older compilers) because of it (Arnd Bergmann).
