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

    This one was present in v2, no changes since then.
