[PATCH 3/3] sched: remove WARN_ON(!sd) from init_sched_groups_power()

From: Viresh Kumar
Date: Tue Jun 11 2013 - 07:07:00 EST

sd can't be NULL in init_sched_groups_power() and so checking it for NULL isn't
useful. In case it is required, then also we need to rearrange the code a bit as
we already accessed invalid pointer sd to get sg: sg = sd->groups.
