Commit c8b1a83605e4 changed the function, making it impossible for callers to be able to tell whether a non-negative return value means "physical function address found and parsed correctly" or "couldn't find corresponding physical function". The important difference between the two being that, in the latter case, the returned pointer is NULL and should never, ever be dereferenced. In order to cope with these changes, the callers have to be updated.
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
