cpufreq: docs: Add missing cpuinfo_cur_freq description
Add a description of the cpuinfo_cur_freq policy attribute in sysfs to the cpufreq documentation under Documentation/admin-guide/pm/ as it is missing after commit 2a0e49279850 (cpufreq: User/admin documentation update and consolidation) that overlooked it. Fixes: 2a0e49279850 (cpufreq: User/admin documentation update and consolidation) Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
