There are 2 issues here: - if one of the 'of_parse_phandle' fails, calling 'mop500_of_node_put()' is a no-op because the 'mop500_dai_links' structure has not been initialized yet, so the referenced are not decremented - The reference stored in 'mop500_dai_links[i].codecs' is refcounted only once in the probe and must be decremented only once.
