Re: [PATCH 2/7] ASoC: codecs: ES8389: Fix the issue about mclk_src

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 4 potential issue(s) to consider:

Pre-existing issues:
- [High] Incorrect sysclk calculation for SCLK mode due to using params_width() instead of params_physical_width() or snd_soc_params_to_bclk().
- [High] Component probe function ties devm_ allocations to the I2C device, causing memory and resource leaks on ASoC card unbind/rebind.
- [High] Regulators are enabled in component probe but never disabled in component remove, leading to regulator enable count leaks.
- [High] Silent failure when valid clock coefficients are not found.

[Severity: High]
This isn't a bug introduced by this patch, but does this calculate the
sysclk correctly for SCLK mode?

It looks like params_width() returns the semantic sample width (e.g., 24
for S24_LE), rather than the physical slot width on the I2S bus
(typically 32 bits for 24-bit samples).

Could this result in an incorrectly calculated sysclk, causing get_coeff()
to fail or configure incorrect clock dividers? Should this use
params_physical_width() or snd_soc_params_to_bclk() instead?

Later in this same function:

sound/soc/codecs/es8389.c:es8389_pcm_hw_params() {
    ...
	coeff = get_coeff(es8389->vddd, dmic_enable, es8389->sysclk, params_rate(params));
	if (coeff >= 0) {
        ...
	} else {
		dev_warn(component->dev, "Clock coefficients do not match");
	}

	return 0;
}

[Severity: High]
This is a pre-existing issue, but does this safely handle errors?

If get_coeff() fails to find valid clock coefficients and returns -EINVAL,
the driver logs a warning but unconditionally returns 0 (success) to the
ALSA core.

Will this cause the audio framework to proceed with an unconfigured codec,
resulting in silent failures or garbled audio? Should it propagate the error
code instead?

[Severity: High]
This isn't a bug introduced by this patch, but does es8389_probe() leak
resources during ASoC card unbind/rebind?

This is an ASoC component probe callback (executed when the sound card
binds), not an I2C driver probe callback. However, later in this
function, it allocates devm resources tied to the I2C device:

sound/soc/codecs/es8389.c:es8389_probe() {
    ...
	ret = devm_regulator_bulk_get(component->dev, ARRAY_SIZE(es8389_core_supplies), es8389->core_supply);
    ...
	es8389->mclk = devm_clk_get_optional(component->dev, "mclk");
    ...
}

Since the I2C device's lifecycle spans beyond the sound card's lifecycle,
every time the sound card is unbound and rebound, won't es8389_probe()
execute again, allocating new regulators and clock handles on the I2C
device's devres list without freeing the previous ones?

Furthermore, this probe function enables the regulators:

sound/soc/codecs/es8389.c:es8389_probe() {
    ...
	ret = regulator_bulk_enable(ARRAY_SIZE(es8389_core_supplies), es8389->core_supply);
    ...
}

[Severity: High]
This is a pre-existing issue, but does this leak the regulator enable count?

The corresponding es8389_remove() function does not call
regulator_bulk_disable():

sound/soc/codecs/es8389.c:es8389_remove() {
	struct es8389_private *es8389 = snd_soc_component_get_drvdata(component);

	regmap_write(es8389->regmap, ES8389_MASTER_MODE, 0x28);
	regmap_write(es8389->regmap, ES8389_HPSW, 0x00);
    ...
}

Every time the ASoC component is bound and then unbound, won't the
regulator's internal enable count be incremented but never decremented?
Could this prevent the regulator from ever being powered off by the system,
leading to increased power consumption?

ASoC: codecs: ES8389: Fix the issue about mclk_src

This commit fixes an issue with incorrect modifications to the mclk_src
variable. It changes mclk_src to a boolean and reads it using
device_property_read_bool, simplifying the MCLK configuration logic.

[Severity: High]
This is a pre-existing issue, but does this calculation yield the correct
physical BCLK rate?

Using params_width() returns the logical sample width (e.g., 24 for S24_LE)
instead of the physical wire width, and this ignores TDM slot configurations.

This could result in calculating a lower SCLK frequency than what is
physically driven on the bus, leading to an incorrect sysclk and the wrong
internal clock dividers.

Should this use snd_soc_params_to_bclk(params) instead?


Also in sound/soc/codecs/es8389.c:es8389_set_dai_fmt():

	switch (fmt & SND_SOC_DAIFMT_CLOCK_PROVIDER_MASK) {
	case SND_SOC_DAIFMT_CBC_CFP:
		regmap_update_bits(es8389->regmap, ES8389_MASTER_MODE,
				ES8389_MASTER_MODE_EN, ES8389_MASTER_MODE_EN);
		es8389->mastermode = 1;
		break;
	case SND_SOC_DAIFMT_CBC_CFC:
		es8389->mastermode = 0;
		break;

[Severity: High]
This is a pre-existing issue, but does the transition to slave mode properly
clear the hardware state?

When SND_SOC_DAIFMT_CBC_CFC is requested, the internal mastermode variable is
updated, but it appears ES8389_MASTER_MODE_EN is not cleared in the
ES8389_MASTER_MODE register. If the codec was previously set to master mode,
could this leave it incorrectly operating as a clock provider and cause bus
contention?


Later in sound/soc/codecs/es8389.c:es8389_pcm_hw_params():

	coeff = get_coeff(es8389->vddd, dmic_enable, es8389->sysclk, params_rate(params));
	if (coeff >= 0) {
		...
		regmap_write(es8389->regmap, ES8389_SYSTEM19, coeff_div[coeff].Reg0x19);
	} else {
		dev_warn(component->dev, "Clock coefficients do not match");
	}

	return 0;

[Severity: High]
This is a pre-existing issue, but should this function return an error code
when get_coeff() fails?

Currently, if get_coeff() fails to find a matching configuration, it prints a
warning but unconditionally returns 0. Could this cause the ALSA core to
assume the hardware is correctly configured and proceed to start the stream,
potentially resulting in silent or distorted audio?

[Severity: High]
This is a pre-existing issue, but does this code handle regmap_read()
failures correctly?

If regmap_read() fails (e.g. due to I2C/SPI communication errors), it
returns a negative error code and leaves reg uninitialized. This
uninitialized stack memory is then permanently saved to es8389->version
and could affect later logic.

There appear to be a few other places in this file with the same pattern
where uninitialized stack memory might be used if regmap_read() fails:

es8389_pcm_hw_params():
	regmap_read(es8389->regmap, ES8389_DMIC_EN, &regv);
	dmic_enable = regv >> 7 & 0x01;

es8389_mute():
	regmap_read(es8389->regmap, ES8389_CSM_STATE1, &regv);
	if (regv != ES8389_STATE_ON) {

es8389_resume():
	regmap_read(es8389->regmap, ES8389_RESET, &regv);
	if (regv == 0xff)

Could we check the return value of regmap_read() in these locations to
avoid evaluating garbage data?

[Severity: High]
This is a pre-existing issue, but does the modulo 2 arithmetic in get_coeff()
unintentionally treat 0 as a wildcard alongside 2?

Looking at get_coeff():

    vddd_det |= ~(coeff_div[i].dvdd_vol % 2) & 0x01;
    dmic_det |= ~(coeff_div[i].dmic_sel % 2) & 0x01;

Since 0 % 2 is 0, this causes ~0 & 1, which evaluates to 1.

This means a row specifying dmic_sel = 0 (like the newly added row above)
will incorrectly match requests where dmic = 1.

Similarly, if an earlier row specifies 0, will it shadow subsequent rows by
acting as a wildcard instead of an exact match?

[Severity: Medium]
Devicetree is typically reserved for describing hardware topology, while
software-configurable tuning parameters like an ADC High Pass Filter are
usually exposed as ALSA kcontrols. Should these HPF values be registered as
mixer controls instead of devicetree properties so userspace can dynamically
adjust them at runtime?

[Severity: Medium]
Could using device_property_read_u8() here lead to a silent misconfiguration
if standard 32-bit devicetree cells are used?

If a devicetree specifies the property as a standard cell, for example:
    everest,hpfl = <10>;

The read_u8 function will read the first zero-padded byte (0x00) and return
success instead of an error. This means the fallback to ES8389_HPF_DEFAULT
will be bypassed, and the hardware will be configured with 0 instead. Would
it be safer to read this as a u32 using device_property_read_u32() and then
cast or bounds-check the result?

[Severity: High]
This is a pre-existing issue, but does defaulting to true for all other
registers omit key configuration registers from the cache?

Because volatile registers are skipped by regcache_sync() during resume,
registers such as ES8389_MASTER_MODE, TDM settings, and clock dividers will
not be restored if they are treated as volatile. Could this break the audio
formatting and cause playback or capture to fail after a suspend and resume
cycle?

[Severity: High]
This is a pre-existing issue, but does the lack of a return value check on
regmap_read() leave regv uninitialized if the I2C read fails?

If the read fails, evaluating the uninitialized stack variable regv will
unpredictably dictate whether a full hardware initialization is performed.

This same pattern appears to exist in other places as well:

sound/soc/codecs/es8389.c:es8389_init() {
    ...
    regmap_read(es8389->regmap, ES8389_MAX_REGISTER, &reg);
    es8389->version = reg;
    ...
}

and

sound/soc/codecs/es8389.c:es8389_mute() {
    ...
    regmap_read(es8389->regmap, ES8389_CSM_STATE1, &regv);
    if (regv != ES8389_STATE_ON) {
    ...
}

Could these lead to inconsistent hardware states or silent audio failures?

[Severity: High]
This is a pre-existing issue, but does this incorrectly calculate the
physical BCLK frequency?

Using params_width() returns the sample data width instead of the physical
slot width on the wire. When mclk_src is set, es8389->sysclk acts as the MCLK
derived from SCLK.

By under-calculating the physical SCLK, the get_coeff() function is provided
with an incorrect MCLK frequency assumption, which can lead to the selection
of wrong internal clock dividers and distorted or missing audio.

Could the physical BCLK be calculated using snd_soc_params_to_bclk(params)
instead?

>  	}

Additionally, I noticed a few other pre-existing issues in this driver:

[Severity: High]
This isn't a bug introduced by this patch, but is there a missing check on the
return value of regmap_read() during resume?

In es8389_resume():

static int es8389_resume(struct snd_soc_component *component)
{
	...
	unsigned int regv;

	regcache_cache_only(es8389->regmap, false);
	regcache_cache_bypass(es8389->regmap, true);
	regmap_read(es8389->regmap, ES8389_RESET, &regv);

	if (regv == 0xff)
	...
}

If the I2C read fails during resume, the stack variable regv is left
uninitialized and evaluated against 0xff. Could this introduce undefined
behavior and lead to incorrect skipping or triggering of the hardware
re-initialization?


[Severity: High]
This isn't a bug introduced by this patch, but are the regulators enabled
during probe leaked on removal?

es8389_probe() successfully enables core regulators:

static int es8389_probe(struct snd_soc_component *component)
{
	...
	ret = regulator_bulk_enable(ARRAY_SIZE(es8389_core_supplies),
				    es8389->core_supply);
	...
}

However, es8389_remove() does not call the corresponding
regulator_bulk_disable().

Since devm_regulator_bulk_get() only automatically frees the handles but does
not implicitly disable the regulators, this leaks the regulator enable
reference count. Could this cause the power domains to remain permanently on
even when the module is unbound or removed?

Due to the chip design,
I don't want users to adjust the HPF while the device is in use.
Therefore, I don¡¯t want to make the HPF a kcontrol setting.

I don't think this is a good approach. 
If it's set to u32, I still won't be able to detect if a user has configured it incorrectly in the DTS.
I still believe it should be set to u8,
and that instructions on how to configure this parameter should be included in Documentation/devicetree/bindings.
