Subject[PATCH 46/46] kernel: Add prototype declaration to header file include/linux/sched.h
Add prototype declaration of function to header file
include/linux/sched.h because it is used by more than one file.

This eliminates the following warning in kernel/sched/fair.c:
kernel/sched/fair.c:5254:22: warning: no previous prototype for ‘arch_scale_freq_power’ [-Wmissing-prototypes]
