With dependencies on full_name containing the entire device node path
removed, stop storing the full_name in nodes created by
dlpar_configure_connector() and pSeries_reconfig_add_node().

...

dn =3D kzalloc(sizeof(*dn), GFP_KERNEL);
	if (!dn)
		return NULL;
=20
	name =3D (char *)ccwa + be32_to_cpu(ccwa->name_offset);
-	dn->full_name =3D kasprintf(GFP_KERNEL, "%s/%s", path, name);
+	dn->full_name =3D kasprintf(GFP_KERNEL, "%s", name);

Isn't this just strdup()?
Perhaps you should rename full_name to name - since it is no longer 'full'?

Maybe you could do a single malloc() for both 'dn' and the name?
