[PATCH] sched.h: Remove useless `const' from function return type

From: Maciej W. Rozycki

This fixes:

cc1: warnings being treated as errors
In file included from include/linux/ptrace.h:5,
from arch/mips/kernel/cpu-probe.c:16:
include/linux/sched.h:1002: warning: type qualifiers ignored on function return type
make[2]: *** [arch/mips/kernel/cpu-probe.o] Error 1

This is a regression introduced with commit
143e1e28cb40bed836b0a06567208bd7347c9672 [sched: Rework sched_domain
topology definition]. The warning itself is benign except in places like
the arch/mips subtree where we use `-Werror' to enforce good coding
practices. Apparently the warning is GCC-version specific, some versions
produce it and some do not.

Vincent,

Did you mean:

typedef int __attribute__((const)) (*sched_domain_flags_f)(void);

by any chance?
