Subject: linux-next: build warning after merge of the tip tree

Hi all,

After merging the tip tree, today's linux-next build (x86_64 allmodconfig)
produced this warning:

kernel/sched.c: In function 'sched_destroy_group':
kernel/sched.c:8098: warning: 'i' is used uninitialized in this function
kernel/sched.c:8088: note: 'i' was declared here

Introduced by commit 3d4b47b4b040c9d77dd68104cfc1055d89a55afd ("sched:
Implement on-demand (active) cfs_rq list").  I think this is a real bug.

[The wrong function is mentioned above, the actual function is
unregister_fair_sched_group() - presumably gcc has confused itself via
inlining.]
