3.16.7-ckt19 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Stratos Karafotis <stratosk@semaphore.gr>
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.
