commit c152f8491a8d9 ("ASoC: audio-graph-card: fix an use-after-free in graph_get_dai_id()") fixups use-after-free issue, but, it need to use "const" for reg. This patch adds it.
We will have below without this patch
LINUX/sound/soc/generic/audio-graph-card.c: In function 'graph_get_dai_id': LINUX/sound/soc/generic/audio-graph-card.c:87:7: warning: assignment discards\ 'const' qualifier from pointer target type [-Wdiscarded-qualifiers] reg = of_get_property(node, "reg", NULL);
