devcg: remove parent_cgroup.
In devcgroup_css_alloc(), there is no longer need for parent_cgroup. bd2953ebbb("devcg: propagate local changes down the hierarchy") made the variable parent_cgroup redundant. This patch removes parent_cgroup from devcgroup_css_alloc(). Signed-off-by: Rami Rosen <ramirose@gmail.com> Acked-by: Aristeu Rozanski <aris@redhat.com> Signed-off-by: Tejun Heo <tj@kernel.org>
