[Xen-devel] [PATCH] libxl: Initialize valid_devs in output_topologyinfo()

[Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>]

Commit e78e8b9bb649 ("libxl: Add interface for querying hypervisor
about PCI topology") neglected to initialize valid_devs. This
may result in not printing a message to console if no IO topology
information is available and, more importantly, may break non-debug
builds on some versions of gcc.
