Subject: [PATCH] ASoC: soc-core: call snd_soc_dapm_debugfs_init() at soc_init_card_debugfs()
Git-commit: d8ca7a0a8583fc491b625450580c4092879af3dd
Patch-mainline: v5.4-rc1
References: jsc#SLE-16518

We have 2 soc_init_card_debugfs() implementations for with/without DEBUG_FS.
But, snd_soc_instantiate_card() calls snd_soc_dapm_debugfs_init() under
ifdef DEBUG_FS after soc_init_card_debugfs(). This is very strange.
We can call snd_soc_dapm_debugfs_init() under soc_init_card_debugfs().

	#ifdef CONFIG_DEBUG_FS
=>	static void soc_init_card_debugfs(...)
	{
		...
	}
	...
	#else
=>	static inline void soc_init_card_debugfs(...)
	{
		...
	}
	#endif

	static int snd_soc_instantiate_card(struct snd_soc_card *card)
	{
		...
=>		soc_init_card_debugfs(card);

*	#ifdef CONFIG_DEBUG_FS
*		snd_soc_dapm_debugfs_init(&card->dapm, card->debugfs_card_root);
*	#endif
	}
