[Cluster-devel] [PATCH dlm-tool 2/4] dlm_controld: fix may be used uninitialized

[Alexander Aring <aahringo@redhat.com>]

This patch fixes the following compiler warning:

daemon_cpg.c:2158:12: warning: ?run? may be used uninitialized in this function [-Wmaybe-uninitialized]
 2158 |   run->info.reply_count++;

It's fixed by just init the used variable to NULL and use it only if
it's not NULL.
