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: imu: bmi160: add IRQF_NO_THREAD to data-ready trigger IRQ

2026-06-29T22:24:47+00:00

bmi160_probe_trigger() registers iio_trigger_generic_data_rdy_poll() through devm_request_irq(), but it passes only irq_type and does not add IRQF_NO_THREAD. When the kernel is booted with forced IRQ threading, the parent IRQ can otherwise be threaded by the IRQ core and the subsequent IIO trigger child IRQ is dispatched from irq/... thread context instead of hardirq context. Because the handler immediately pushes the event into iio_trigger_poll(), this violates the hardirq-only IIO trigger helper contract and can drive downstream trigger consumers through the wrong execution context. Add IRQF_NO_THREAD on top of irq_type when registering the BMI160 data- ready trigger handler.

iio: Initialize i2c_device_id arrays using member names

2026-05-31T10:01:46+00:00

While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

iio: imu: bmi160: Remove potential undefined behavior in bmi160_config_pin()

2026-03-15T12:20:34+00:00

If 'pin' is not one of its expected values, the value of 'int_out_ctrl_shift' is undefined. With UBSAN enabled, this causes Clang to generate undefined behavior, resulting in the following warning: drivers/iio/imu/bmi160/bmi160_core.o: warning: objtool: bmi160_setup_irq() falls through to next function __cfi_bmi160_core_runtime_resume() Prevent the UB and improve error handling by returning an error if 'pin' has an unexpected value. While at it, simplify the code a bit by moving the 'pin_name' assignment to the first switch statement.

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.

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.
