From a134aeaa17ad3618575fac86f27246a3b2466001 Mon Sep 17 00:00:00 2001 From: Wei Liu Date: Mon, 24 Oct 2016 11:11:15 +0100 Subject: [PATCH] libxl: initialise nr_dom_vcpus to fix 4a6070ea9 Clang complains nr_dom_vcpus may be used uninitialised after 4a6070ea9. The real issue is vinfo can be NULL and nr_dom_vcpus remains uninitialised if previous call fails. Initialise nr_dom_vcpus to 0 at the beginning of the loop to fix the issue.
