[PATCH] sched/fair: Remove unused but set variable 'rq'

From: Tobias Klauser
Date: Wed Oct 26 2016 - 07:37:44 EST


Since commit 8663e24d56dc ("sched/fair: Reorder cgroup creation code"),
the variable rq in alloc_fair_sched_group is set but no longer used.
Remove it to fix the following GCC warning when building with 'W=1':

kernel/sched/fair.c:8842:13: warning: variable ârqâ set but not used [-Wunused-but-set-variable]
