[PATCH 5.15 591/779] ASoC: qcom: Fix missing of_node_put() in asoc_qcom_lpass_cpu_platform_probe()

[Greg Kroah-Hartman]

From: Liang He <windhl@xxxxxxx>

[ Upstream commit f507c0c67dac57d2bcd5dcae4b6139b0305d8957 ]

We should call of_node_put() for the reference 'dsp_of_node' returned by
of_parse_phandle() which will increase the refcount.

Fixes: 9bae4880acee ("ASoC: qcom: move ipq806x specific bits out of lpass driver.")
