Subject: logind: don't print error if devices vanish during ACL-init
X-Git-Tag: v213~486

logind: don't print error if devices vanish during ACL-init

If a device is unplugged while we initialize it, we will get ENOENT for
ACL-init (and related stuff). We currently print errors then, which is
misleading. Print a debug-message early and continue.
