Subject: udev: downgrade log level when running without cgroup
X-Git-Tag: v254-rc3~18
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=01b030c2018a6dcdc7003587fa34aa8acd8dc0e2;p=thirdparty%2Fsystemd.git

udev: downgrade log level when running without cgroup

The cgroup path is optional, hence it is not necessary to warn the
failure loudly.

Follow-up for f8371dbd56d27621932ecbe3f5c1246e925fd53a.

Closes #28469.
