ASoC: codec: Remove ak4641

2026-01-27T12:45:54+00:00

Since commit d6df7df7ae5a0 ("ARM: pxa: remove unused board files"), there has been no in-tree user of the AK4641 codec driver. The last user (HP iPAQ hx4700) was a non-DT PXA board file that instantiated the device via I2C board data; that code was removed as part of the PXA board-file purge. The AK4641 driver was introduced ~2011 and still probes only via the I2C device-ID table ('.id_table'), without an 'of_match_table', so there are no upstream Devicetree users to retain. With no in-tree users left, remove the driver.

ASoC: codecs: ak4641: use snd_kcontrol_chip() instead of snd_soc_kcontrol_component()

2025-10-20T01:42:20+00:00

We have very similar name functions (A)(B). Both gets component from snd_kcontrol, but (A) is used in callback functions which is registered through snd_soc_add_component_controls(), (B) is used through snd_soc_dapm_new_widgets(). (A) snd_soc_kcontrol_component() (B) snd_soc_dapm_kcontrol_component() (B) is using very picky way to get component but using it is necessary in ASoC. But (A) is just wrapper function to snd_kcontrol_chip(), and directly using it without wrapper is very common way on ALSA. To reduce confusions of similar function, let's use common way on (A).

ASoC: codecs: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-03T02:08:06+00:00

These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own.

ASoC: Switch i2c drivers back to use .probe()

2023-05-07T23:48:49+00:00

After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

i2c: Make remove callback return void

2022-08-16T10:46:26+00:00

The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

ASoC: ak*: Remove now redundant non_legacy_dai_naming flag

2022-06-27T12:16:57+00:00

The ASoC core has now been changed to default to the non-legacy DAI naming, as such drivers using the new scheme no longer need to specify the non_legacy_dai_naming flag.

ASoC: ak4*: use simple i2c probe function

2022-04-11T18:18:08+00:00

The i2c probe functions here don't use the id information provided in their second argument, so the single-parameter i2c probe function ("probe_new") can be used instead. This avoids scanning the identifier tables during probes. Signed-off-by: Stephen Kitt Link: https://lore.kernel.org/r/20220405165836.2165310-2-steve@sk2.org Signed-off-by: Mark Brown
