The patch
ASoC: soc-core: remove soc_remove_dai_links()
has been applied to the asoc tree at

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

It is easy to read code if it is cleanly using paired function/naming, like start <-> stop, register <-> unregister, etc, etc. But, current ALSA SoC code is very random, unbalance, not paired, etc. It is easy to create bug at the such code, and it will be difficult to debug.
soc_cleanup_card_resources() (a) which is paired function of snd_soc_instantiate_card() (A) is calling soc_remove_dai_links() (*) to remove card related resources, but it is breaking add/remove balance (B)(b)(C)(c)(D)(d), in other words these should be called from soc_cleanup_card_resources() (a) from balance point of view.
More headacke is that it is using original removing method for dai_link even though we already have snd_soc_remove_dai_link() which is the function for it (d).
This patch removes snd_soc_remove_dai_links() and balance up code.
static void soc_remove_dai_links(...) { ... (b) soc_remove_link_dais(card); (c) soc_remove_link_components(card);
for_each_card_links_safe(card, link, _link) { ... /* it should use snd_soc_remove_dai_link() here */ (d) list_del(&link->list); } }
(a) static int soc_cleanup_card_resources(...) { ...
/* remove and free each DAI */ (*) soc_remove_dai_links(card); ... }
(A) static int snd_soc_instantiate_card(struct snd_soc_card *card) { ... /* add predefined DAI links to the list */ for_each_card_prelinks(card, i, dai_link) (B) snd_soc_add_dai_link(card, dai_link); ... /* probe all components used by DAI links on this card */ (C) ret = soc_probe_link_components(card); ... /* probe all DAI links on this card */ (D) ret = soc_probe_link_dais(card); ... }
