Subject: [PATCH 3.12 053/142] cpufreq: Fix and clean up show_cpuinfo_cur_freq()

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

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

===============

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.
