Decreasing the reference count in device's > remove() to make sure the object is valid for whole sound card's lifecycle. > > [1]: https://elixir.bootlin.com/linux/v5.16-rc5/source/sound/soc/mediatek/mt8195/mt8195-mt6359-rt1019-rt5682.c#L1065 I guess I have found the answer to my original questions. The of_node in snd_soc_dai_link_component in snd_soc_dai_link is mainly for matching the component[4]. snd_soc_component itself should hold the reference count.
