This is a bit confusing. Usually, we use @ret for keeping return value
from the function its defined in. In this specific case, @ret would hold
the retval of qemuBuildSerialChrDeviceProps() and thus would have to be
type of virJSONValue*. If you want to keep an intermediary retval of a
function called from within we use other names, like rc, rv, tmp.

But fortunatelly, we can do without @ret and even without @typestr.

There's no need to remove this code, especially when you're replacing it
with itself. The pattern that we can use here is:

if (virJSONValueObjectAdd(&props, ...) < 0) /* this is the unchanged
    return NULL;                               call */

if (serial->targetModel == ISA_SERIAL &&
    virJSONValueObjectAdd(&props,
                          "k:index", serial->target.port,
                          NULL) < 0)
    return NULL;
