[PATCH RESEND 4.4.y-cip 10/15] PM / OPP: Set cpu_dev->id in cpumask first


Chen-Yu Tsai (Moxa) <wens@...>
 

From: Pi-Cheng Chen <pi-cheng.chen@linaro.org>

Set cpu_dev->id in cpumask first when setting up cpumask for CPUs that
share the same OPP table. This might be helpful when handling cpumask
without the original CPU bitfield set.
