[PATCH] powerpc: Remove leftover cputime_to_nsecs call causing build error

From: Frederic Weisbecker
Date: Tue Feb 21 2017 - 10:19:16 EST


This type conversion is a leftover that got ignored during the kcpustat
conversion to nanosecs, resulting in build breakage with config having
CONFIG_NO_HZ_FULL=y.

arch/powerpc/kernel/time.c: In function 'running_clock':
arch/powerpc/kernel/time.c:712:2: error: implicit declaration of function 'cputime_to_nsecs' [-Werror=implicit-function-declaration]
return local_clock() - cputime_to_nsecs(kcpustat_this_cpu->cpustat[CPUTIME_STEAL]);

All we need is to remove it.
