iio: hid-sensors: align function parenthesis for readability

2026-07-07T02:12:50+00:00

Adjust alignment of parentheses across HID sensor IIO drivers to improve readability and maintain consistency with kernel coding style. While updating the formatting, group related arguments consistently in multi-line function signatures where appropriate. No functional change intended.

Merge tag 'v7.2-rc2' into togreg

2026-07-06T15:59:47+00:00

Linux 7.2-rc2 Done to resolve conflicts with header reorg around mod_devicetable.h and provide a base for other inflight series that touch the includes.

Replace by more specific (c files)

2026-07-03T05:38:17+00:00

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

iio: position: hid-sensor-custom-intel-hinge: use common device for devres

2026-07-02T17:26:39+00:00

kmemdup() is used for memory that is logically tied to the HID platform device, even though the driver binds into the IIO framework. Using &indio_dev->dev for devres allocations works functionally, but it results in two separate devres ownership trees—one for the HID platform device (pdev) and another for the IIO device (indio_dev). The devres framework is intended to have a single, well-defined parent device. Since the memory originates from HID sensor probing and is not IIO-specific, &pdev->dev is the correct and logical owner. Switch to using the platform device for devm_kmemdup() so that all resources are released deterministically and consistently.

iio: hid-sensor-custom-intel-hinge: use u32 instead of unsigned int

Prefer 'u32' instead of 'unsigned int' for usage_id variable. This matches expected callback API type and improves code clarity. No functional change. Signed-off-by: Sanjay Chitroda Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron

iio: normalize array sentinel style

2025-04-22T18:10:04+00:00

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.

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.
