Mike Tipton 388c90c577 interconnect: Treat xlate() returning NULL node as an error ... [ Upstream commit ad2ab1297d ] Currently, if provider->xlate() or provider->xlate_extended() "successfully" return a NULL node, then of_icc_get_from_provider() won't consider that an error and will successfully return the NULL node. This bypasses error handling in of_icc_get_by_index() and leads to NULL dereferences in path_find(). This could be avoided by ensuring provider callbacks always return an error for NULL nodes, but it's better to explicitly protect against this in the common framework.
