Subject: cgroup: fix cgroup_css() invocation in css_from_id()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d1625964da51bda61306ad3ec45307a799c21f08;p=linux.git

cgroup: fix cgroup_css() invocation in css_from_id()

ca8bdcaff0 ("cgroup: make cgroup_css() take cgroup_subsys * instead
and allow NULL subsys") missed one conversion in css_from_id(), which
was newly added.  As css_from_id() doesn't have any user yet, this
doesn't break anything other than generating a build warning.

Convert it.
