iio: light: isl29125: Use iio_push_to_buffers_with_ts() to allow source size runtime check

2025-08-16T14:52:46Z

Also move the structure used as the source to the stack as it is only 16 bytes and not the target of an DMA or similar. Reviewed-by: Matti Vaittinen Reviewed-by: Andy Shevchenko Link: https://patch.msgid.link/20250802164436.515988-10-jic23@kernel.org Signed-off-by: Jonathan Cameron

iio: light: isl29125: Switch to sparse friendly iio_device_claim/release_direct()

2025-04-22T18:09:55Z

These new functions allow sparse to find failures to release direct mode reducing chances of bugs over the claim_direct_mode() functions that are deprecated. Reviewed-by: David Lechner Link: https://patch.msgid.link/20250309170633.1347476-4-jic23@kernel.org Signed-off-by: Jonathan Cameron

iio: light: Use aligned_s64 instead of open coding alignment.

2024-12-28T14:28:15Z

Use this new type to both slightly simplify the code and avoid confusing static analysis tools. Mostly this series is about consistency to avoid this code pattern getting copied into more drivers.

iio: light: isl29125: make use of iio_for_each_active_channel()

2024-08-03T09:13:40Z

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.

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

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.

iio: light: isl29125: Convert to i2c's .probe_new()

2022-11-23T20:20:28Z

The probe function doesn't make use of the i2c_device_id * parameter so it can be trivially converted. Signed-off-by: Uwe Kleine-König Reviewed-by: Andy Shevchenko Link: https://lore.kernel.org/r/20221118224540.619276-128-uwe@kleine-koenig.org Signed-off-by: Jonathan Cameron

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.

iio:light:isl29125: Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() etc

2022-02-18T11:45:29Z

Letting the compiler remove these functions when the kernel is built without CONFIG_PM_SLEEP support is simpler and less error prone than the use of #ifdef based config guards. Removing instances of this approach from IIO also stops them being copied into new drivers.
