commit 3c83ac23253c ("ASoC: hdac_hdmi: check error return") fixes the static checker warning reported by Dan Carpenter: sound/soc/codecs/hdac_hdmi.c:416 hdac_hdmi_parse_and_map_nid() warn: unsigned 'hdac->num_nodes' is never less than zero. But it doesn't fix the issue completely. It's also a failure if no sub nodes found for an afg node. So modify the return condition appropriately. Signed-off-by: Subhransu S.
