Looks to me like the right solution here would be to add
bool initial_domain = xen_initial_domain();
and then s/xen_initial_domain()/initial_domain/ in the rest of the
function. That should make it clear to static analysis tools that
acpi_dev will not be used uninitialized -- since the problem right
now is that they don't know that xen_initial_domain() always returns
the same value -- without having a bogus initialization which could
hide a future bug.
