Subject: login: add a missing error check for session_set_leader()
X-Git-Tag: v242~381
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fe3ab8458b9c0ead4b3e14ac25b342d8c34376fe;p=platform%2Fupstream%2Fsystemd.git

login: add a missing error check for session_set_leader()

session_set_leader() may fail. If it fails, then manager_start_scope()
will trigger assertion.

This may be related to RHBZ#1663704.
