[PATCH 3.10 194/268] cpufreq: Fix and clean up show_cpuinfo_cur_freq()

[Willy Tarreau]

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.
