[PATCH 4.4 20/30] cpufreq: Fix and clean up show_cpuinfo_cur_freq()

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

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

commit 9b4f603e7a9f4282aec451063ffbbb8bb410dcd9 upstream.

There is a missing newline in show_cpuinfo_cur_freq(), so add it,
but while at it clean that function up somewhat too.
