Subject: sd-login: fix return value of sd_pid_get_user_unit
X-Git-Tag: v234~181^2~3
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d440fb97ba36e0a1dcf03e41601e53303a4d6288;p=thirdparty%2Fsystemd.git

sd-login: fix return value of sd_pid_get_user_unit

E.g. "/user.slice/user-1000.slice/session-15.scope" would cause -ENXIO to be
returned.
