iio: accel: Drop unnecessary -ENOMEM messages

2025-08-25T11:28:10Z

The drivers do not require their own error messages for error -ENOMEM, memory allocation failures. So remove the dev_err() messages from the probe(). Signed-off-by: Dixit Parmar Link: https://patch.msgid.link/20250822-enomam_logs-v1-1-db87f2974552@gmail.com Signed-off-by: Jonathan Cameron

iio: Remove single use of macro definition for IRQ name

2025-06-09T06:45:36Z

There is really no reason for having the IRQ name as a macro definition if it is only used once (often in functions requesting the IRQ). It is also more readable this way. Remove these macro definitions and instead use the string literal directly.

iio: accel: Use iio_push_to_buffers_with_ts() to provide length for runtime checks.

2025-05-21T13:20:26Z

This new function allows us to perform debug checks in the helper to ensure that the overrun does not occur. Use it in all the simple cases where either a static buffer or a structure is used in the drivers.

iio: normalize array sentinel style

2025-04-22T18:10:04Z

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace the array sentinel in all IIO drivers to the same style. For some time, we've been trying to consistently use `{ }` (no trailing comma, no comment, one space between braces) for array sentinels in the IIO subsystem. Still nearly 50% of existing code uses a different style. To save reviewers from having to request this trivial change as frequently, let's normalize the style in all existing IIO drivers. At least when code is copy/pasted to new drivers, the style will be consistent.

e4ca0e59c394 ("types: Complement the aligned types with signed 64-bit one") introduced aligned_s64. Use it for all IIO accelerometer drivers.

Use iio_for_each_active_channel() to iterate over active channels accessing '.masklength' so it can be annotated as __private when there are no more direct users of it.

iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0

2024-05-27T08:48:57Z

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. While add it, also remove commas after the sentinel entries.

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

2022-08-16T10:46:26Z

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.
