[alsa-devel] [PATCH resend 01/11] ASoC: soc-core: add comment to jack at soc_remove_component()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Basically, driver which setups snd_soc_component_set_jack() need
to release it by themselves. But, as framework level robustness,
soc_remove_component() also releases it.

To avoid code reader confuse, this patch makes it clarify.

This patch makes it clarify.

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current soc_probe_link_components() implementation is very half,
thus it is very difficult to read.

	for_each_comp_order(xxx) {

This patch does all for_each_xxx() under soc_probe_link_components(),
and makes it to self contained.

[alsa-devel] [PATCH resend 05/11] ASoC: soc-core: move soc_probe_dai() next to soc_remove_dai()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

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.

This patch moves soc_probe_dai() next to soc_remove_dai() which is
paired function.

[alsa-devel] [PATCH resend 06/11] ASoC: soc-core: add new soc_link_init()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current soc_probe_link_dais() (1) is called under probe_order (2),
and it will initialize dai_link related settings at *Last* turn (3)(B).
It is very complex code.

	static int soc_probe_link_dais(..., order)
	{
(A)		/* probe DAIs here */
		...

(3)		if (order != SND_SOC_COMP_ORDER_LAST)
			return 0;

(B)		/* initialize dai_link related settings */
		...
	}

	static int snd_soc_instantiate_card(...)
	{
		...
(2)		for_each_comp_order(order) {
			for_each_card_rtds(...) {
(1)				ret = soc_probe_link_dais(..., order);
			}
		}
	}

This patch separes soc_probe_link_dais() into "DAI probe" portion (A),
and dai_link settings portion (B).
The later is named as soc_link_init() by this patch.

[alsa-devel] [PATCH resend 09/11] ASoC: soc-core: self contained soc_bind_aux_dev()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current soc_bind_aux_dev() implementation is very half,
thus it is very unreadable.

	for_each_card_pre_auxs(xxx) {
=>		ret = soc_bind_aux_dev(xxx);
		...
	}

This patch does all for_each_xxx() under soc_bind_aux_dev(),
and makes it to self contained.

[alsa-devel] [PATCH resend 10/11] ASoC: soc-core: add soc_unbind_aux_dev()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

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-core.c has soc_bind_aux_dev(), but, there is no its paired
soc_unbind_aux_dev().
This patch adds soc_unbind_aux_dev().

[alsa-devel] [PATCH resend 11/11] ASoC: soc-core: self contained soc_unbind_aux_dev()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current soc_unbind_aux_dev() implementation is very half,
thus it is very unreadable.

	for_each_comp_order(order) {
		for_each_card_auxs_safe(card, comp, _comp) {

(1)			if (comp->driver->remove_order == order) {
				...
=>				soc_unbind_aux_dev(comp);
			}
	}

soc_unbind_aux_dev() itself is not related to remove_order (1).
And, it is called from soc_remove_aux_devices(), even though
its paired function soc_bind_aux_dev() is called from
snd_soc_instantiate_card().
It is very unbalance, and very difficult to understand.

This patch do
1) update soc_bind_aux_dev() to self contained
2) call it from soc_cleanup_card_resources() to make up balance

The patch

   ASoC: soc-core: add comment to jack at soc_remove_component()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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.

Please add any relevant lists and maintainers to the CCs when replying

Subject: [PATCH] ASoC: soc-core: add comment to jack at soc_remove_component()

Basically, driver which setups snd_soc_component_set_jack() need
to release it by themselves. But, as framework level robustness,
soc_remove_component() also releases it.

To avoid code reader confuse, this patch makes it clarify.

This patch makes it clarify.

Subject: [PATCH] ASoC: soc-core: add new soc_link_init()

Current soc_probe_link_dais() (1) is called under probe_order (2),
and it will initialize dai_link related settings at *Last* turn (3)(B).
It is very complex code.

	static int soc_probe_link_dais(..., order)
	{
(A)		/* probe DAIs here */
		...

(3)		if (order != SND_SOC_COMP_ORDER_LAST)
			return 0;

(B)		/* initialize dai_link related settings */
		...
	}

	static int snd_soc_instantiate_card(...)
	{
		...
(2)		for_each_comp_order(order) {
			for_each_card_rtds(...) {
(1)				ret = soc_probe_link_dais(..., order);
			}
		}
	}

This patch separes soc_probe_link_dais() into "DAI probe" portion (A),
and dai_link settings portion (B).
The later is named as soc_link_init() by this patch.

[alsa-devel] Applied "ASoC: soc-core: self contained soc_probe_link_dais()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-core: self contained soc_probe_link_dais()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Subject: [PATCH] ASoC: soc-core: move soc_probe_link_dais() next to
 soc_remove_link_dais()

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.

This patch moves soc_probe_link_dais() next to soc_remove_link_dais()
which is paired function.

Subject: [PATCH] ASoC: soc-core: add soc_unbind_aux_dev()

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-core.c has soc_bind_aux_dev(), but, there is no its paired
soc_unbind_aux_dev().
This patch adds soc_unbind_aux_dev().

[alsa-devel] Applied "ASoC: soc-core: self contained soc_bind_aux_dev()" to the asoc tree

[Mark Brown]

The patch

   ASoC: soc-core: self contained soc_bind_aux_dev()

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Subject: [PATCH] ASoC: soc-core: self contained soc_bind_aux_dev()

Current soc_bind_aux_dev() implementation is very half,
thus it is very unreadable.

	for_each_card_pre_auxs(xxx) {
=>		ret = soc_bind_aux_dev(xxx);
		...
	}

This patch does all for_each_xxx() under soc_bind_aux_dev(),
and makes it to self contained.

Subject: [PATCH] ASoC: soc-core: self contained soc_unbind_aux_dev()

Current soc_unbind_aux_dev() implementation is very half,
thus it is very unreadable.

	for_each_comp_order(order) {
		for_each_card_auxs_safe(card, comp, _comp) {

(1)			if (comp->driver->remove_order == order) {
				...
=>				soc_unbind_aux_dev(comp);
			}
	}

soc_unbind_aux_dev() itself is not related to remove_order (1).
And, it is called from soc_remove_aux_devices(), even though
its paired function soc_bind_aux_dev() is called from
snd_soc_instantiate_card().
It is very unbalance, and very difficult to understand.

This patch do
1) update soc_bind_aux_dev() to self contained
2) call it from soc_cleanup_card_resources() to make up balance
