From 2246ca53d7b3c286348c9c4cc4d2551972619cc2 Mon Sep 17 00:00:00 2001 From: Miaohe Lin Date: Sat, 1 Jul 2023 15:38:56 +0800 Subject: cgroup: remove unneeded return value of cgroup_rm_cftypes_locked() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The return value of cgroup_rm_cftypes_locked() is always 0. So remove it to simplify the code. No functional change intended.
