[PATCH 5.19 0941/1157] ASoC: audio-graph-card2.c: use of_property_read_u32() for rate

[Greg Kroah-Hartman]

From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx>

[ Upstream commit 817a62108dfacebd548e38451bf0e7eee023e97f ]

Audio Graph Card2 is using of_get_property(), but it should use
of_property_read_u32() to getting rate. Otherwise the setting will be
strange value. This patch fixup it.
