From: Liang He <windhl@126.com> stable inclusion from stable-v5.10.137 commit 2f735069cdc16fe132b7ffebed0f05e4db9a57c2 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I60PLB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ 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.")
