ASoC: audio-graph-card: add missing const at graph_get_dai_id()
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); Fixes: c152f8491a8d9 ("ASoC: audio-graph-card: fix an use-after-free in graph_get_dai_id()") Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Acked-by: Wen Yang <wen.yang99@zte.com.cn> Link: https://lore.kernel.org/r/87sgrd43ja.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
