[PATCH 3.16.y-ckt 065/104] cpufreq: intel_pstate: Remove unnecessary type casting in div_s64() call

From: Luis Henriques

3.16.7-ckt19 -stable review patch. If anyone has any objections, please let me know.


From: Stratos Karafotis <stratosk@xxxxxxxxxxxx>

commit fa30dff9a81ea9fdc2e985a14fe14ce6393a3214 upstream.

div_s64() accepts the divisor parameter as s32. Helper div_fp()
also accepts divisor as int32_t.

So, remove the unnecessary int64_t type casting.
