[PATCH v4 4/7] cpufreq: Move governor attribute set headers to cpufreq.h

Rafael J. Wysocki
2016-03-16T15:02:45Z

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Move definitions and function headers related to struct gov_attr_set
to include/linux/cpufreq.h so they can be used by (future) goverernors
located outside of drivers/cpufreq/.

No functional changes.
