commit d685aea5e0a8 ("ASoC: audio-graph-card2: fix off by one in graph_parse_node_multi_nm()") uses ">=" instead of ">" for index check, but it was wrong. The nm_idx will be increment at end of loop, thus, ">" is correct.
while (1) { ... => if (*nm_idx > nm_max) break; ... (*nm_idx)++; }
Without this patch, "Multi-Codec-1" sample on ${LINUX}/sound/soc/generic/audio-graph-card2-custom-sample.dtsi will be error.
