iio: Replace IRQF_ONESHOT with IRQF_NO_THREAD

2026-01-29T16:11:50+00:00

Passing IRQF_ONESHOT ensures that the interrupt source is masked until the secondary (threaded) handler is done. If only a primary handler is used then the flag makes no sense because the interrupt can not fire (again) while its handler is running. The flag also disallows force-threading of the primary handler and the irq-core will warn about this. The intention here was probably not allowing forced-threading for handlers such as iio_trigger_generic_data_rdy_poll() will intends to invoke hard-interrupt handlers. Replace IRQF_ONESHOT with IRQF_NO_THREAD. Reviewed-by: Andy Shevchenko Reviewed-by: Marcus Folkesson Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Jonathan Cameron

iio: temperature: tmp006: use = { } instead of memset()

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

2025-05-21T13:20:26+00:00

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: temperature: tmp006: Stop using iio_device_claim_direct_scoped()

2025-02-17T12:57:31+00:00

This complex cleanup.h use case of conditional guards has proved to be more trouble that it is worth in terms of false positive compiler warnings and hard to read code. Move directly to the new claim/release_direct() that allow sparse to check for unbalanced context.

iio: temperature: tmp006: Use aligned_s64 instead of open coding alignment.

2024-12-28T14:28:14+00:00

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: temperature: tmp006: fix information leak in triggered buffer

2024-12-08T16:51:35+00:00

The 'scan' local struct is used to push data to user space from a triggered buffer, but it has a hole between the two 16-bit data channels and the timestamp. This hole is never initialized. Initialize the struct to zero before using it to avoid pushing uninitialized information to userspace.

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

2024-05-27T08:48:57+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. While add it, also remove commas after the sentinel entries.
