iio: temp: maxim-thermocouple: Fix potential lack of DMA safe buffer.

2025-04-18T15:05:06+00:00

The trick of using __aligned(IIO_DMA_MINALIGN) ensures that there is no overlap between buffers used for DMA and those used for driver state storage that are before the marking. It doesn't ensure anything above state variables found after the marking. Hence move this particular bit of state earlier in the structure.

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.

module: Convert symbol namespace to string literal

Clean up the existing export namespace code along the same lines of commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")") and for the same reason, it is not desired for the namespace argument to be a macro expansion itself.

iio: fix write_event_config signature

2024-11-03T20:33:44+00:00

write_event_config callback use an int for state, but it is actually a boolean. iio_ev_state_store is actually using kstrtobool to check user input, then gives the converted boolean value to write_event_config. Fix signature and update all iio drivers to use the new signature. This patch has been partially written using coccinelle with the following script: $ cat iio-bool.cocci // Options: --all-includes virtual patch @c1@ identifier iioinfo; identifier wecfunc; @@ static const struct iio_info iioinfo = { ..., .write_event_config = ( wecfunc | &wecfunc ), ..., }; @@ identifier c1.wecfunc; identifier indio_dev, chan, type, dir, state; @@ int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir, -int +bool state) { ... } make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio Unfortunately, this script didn't match all files: * all write_event_config callbacks using iio_device_claim_direct_scoped were not detected and not patched. * all files that do not assign and declare the write_event_config callback in the same file. iio.h was also manually updated. The patch was build tested using allmodconfig config. cc: Julia Lawall Signed-off-by: Julien Stephan Link: https://patch.msgid.link/20241031-iio-fix-write-event-config-signature-v2-7-2bcacbb517a2@baylibre.com Signed-off-by: Jonathan Cameron

iio: Switch back to struct platform_driver::remove()

2024-10-10T18:31:50+00:00

After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/iio/ to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer. While touching these files, make indention of the struct initializer consistent in several files.
