Subject: resolve: set error code on failure
X-Git-Tag: v218~301
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=59aa582137cab11ff6aeb9adc56b9e70c4d320ae;p=elogind.git

resolve: set error code on failure

Set the error code in case of incorrect name. This prevents continuing
and failing an assert(name) later on.
