* ASoC: codecs: Drop explicit initialization of struct ↵Uwe Kleine-König2024-05-031-1/+1
| | | | | | | | | | | | | | | | i2c_device_id::driver_data to 0 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: cs42l51: fix driver to properly autoload with automatic module loadingThomas Petazzoni2023-07-171-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 2cb1e0259f50 ("ASoC: cs42l51: re-hook of_match_table pointer"), 9 years ago, some random guy fixed the cs42l51 after it was split into a core part and an I2C part to properly match based on a Device Tree compatible string. However, the fix in this commit is wrong: the MODULE_DEVICE_TABLE(of, ....) is in the core part of the driver, not the I2C part. Therefore, automatic module loading based on module.alias, based on matching with the DT compatible string, loads the core part of the driver, but not the I2C part. And threfore, the i2c_driver is not registered, and the codec is not known to the system, nor matched with a DT node with the corresponding compatible string. In order to fix that, we move the MODULE_DEVICE_TABLE(of, ...) into the I2C part of the driver. The cs42l51_of_match[] array is also moved as well, as it is not possible to have this definition in one file, and the MODULE_DEVICE_TABLE(of, ...) invocation in another file, due to how MODULE_DEVICE_TABLE works. Thanks to this commit, the I2C part of the driver now properly autoloads, and thanks to its dependency on the core part, the core part gets autoloaded as well, resulting in a functional sound card without having to manually load kernel modules.

* ASoC: Switch i2c drivers back to use .probe()Uwe Kleine-König2023-05-081-1/+1
| | | | | | | | | | | | 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 voidUwe Kleine-König2022-08-161-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: cs*: use simple i2c probe functionStephen Kitt2022-04-051-3/+2
| | | | | | | | | | | | | | | 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.

* ASoC: cs42l51: Improve error handling in cs42l51_remove()Uwe Kleine-König2022-01-281-1/+3
| | | | | | | | | | | | | | | | | | | When disabling a regulator fails while the device goes away, there is little we can do and the machine is probably in enough trouble that any action we'd want to take fails anyhow. The return value used to be passed on in cs42l51_i2c_remove() (i.e. the i2c device remove callback). But the i2c core ignores the error code (apart from emitting a generic warning) and removes the device anyhow. So return 0 unconditionally in cs42l51_i2c_remove(), and instead of returning the error code to the upper layer emit a more helpful warning message. After that nobody is interested any more in the actual error code, so let cs42l51_remove() return void.

| | | | | | | | | | | | | | | | | | In commit a1253ef6d3fa ("ASoC: cs42l51: split i2c from codec driver"), the I2C part of the CS42L51 was moved to a separate file, but the definition of the of_device_id array was left in the driver file itself, no longer connected to the platform_driver structure using the .of_match_table pointer. This commit exports the of_device_id array in cs42l51, and uses it as .of_match_able in cs42l51-i2c.c. This solution was suggested by Brian Austin.
