iio: position: iqs624: use devm_blocking_notifier_chain_register()

2026-09-04T02:55:53+00:00

Replace the blocking_notifier_chain_register() + devm_add_action_or_reset() pattern with a single call to devm_blocking_notifier_chain_register(), removing the iqs624_pos_notifier_unregister() callback. Signed-off-by: Eliav Farber Signed-off-by: Jonathan Cameron

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: 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
