Subject: [PATCH] ASoC: soc-core: call list_del(&rtd->list) at soc_free_pcm_runtime()
Git-commit: 753ace0a34fbd39ac2ec654c6859823db420f69e
Patch-mainline: v5.5-rc1
References: jsc#SLE-16518

Current ALSA SoC is calling list_del(&rtd->list) at (1)

	static void soc_remove_pcm_runtimes(...)
	{
		...
		for_each_card_rtds_safe(card, rtd, _rtd) {
(1)			list_del(&rtd->list);
(2)			soc_free_pcm_runtime(rtd);
		}
		...
	}

But, we will call soc_free_pcm_runtime() after that (2).
&rtd->list is         connected at soc_new_pcm_runtime(),
Thus, it should be disconnected at soc_free_pcm_runtime().

This patch calls list_del(&rtd->list) at soc_free_pcm_runtime().
