Subject: Re: [PATCH v3 2/2] cpufreq: Documentation update for trace_policy_frequency

Hi Sam,

IMO this type of documentation should be in the same patch as the
related change because having a single commit makes it easier to track
(especially if/when these changes are cherry-picked to other
trees). There may be reasons to keep them separate that I'm not thinking
of, so if others disagree, defer to them!

Otherwise, this change lgtm.
