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: 2nd set of fixes for the 7.1 cycle. Usual mixed bag of ancient issues and the recently introduced. Various drivers - Ensure use of simple_write_to_buffer() in debugfs callbacks doesn't result in reading off the end of intended data by checking the position is always 0. buffer/hw-consumer - Ensure scan_mask is freed on buffer release. acpi-als - Check ACPI_COMPANION() against NULL to close corner case where a driver is overridden. adi,ad4062 - Add GPIOLIB dependency to avoid undefined ref to gpiochip_get_data() adi.ad7768-1 - Add GPIOLIB dependency to avoid several undefined functions. adi,ad2s1210 - Ensure possible recovery path if a read fails in the interrupt handler. bosch,bmg160 - Increase sleep on startup to ensure device is ready. bosch,bmp280 - Ensure buffer pushed to kfifo is zeroed to avoid leaking uninitialized stack data to userspace. dyna-image,al3010 - Fix refactor that stopped reading one of the two measurement registers. dyna-image,al3320a - Fix refactor that stopped reading one of the two measurement registers. qcom,spmi-iadc - Ensure disable_irq_wake() is called on remove path. sensiron,scd30 - Fix a sign extension bug. st,vl5310x - Ensure possible recovery path if a read fails in the interrupt handler. ti,adc1298 - Bounds check for pga_settings index. Hardening against device returning unexpected values. ti,tmp006 - Ensure trigger correctly released on remove path. vishay,veml6030 - Fix incorrect channel type in events. vishay,veml6074 - Bounds check for veml6075_it_ms.

iio: chemical: scd30: Replace manual locking with RAII locking

2026-06-03T13:54:08+00:00

scd30_core.c currently uses manual mutex_lock() and mutex_unlock() calls. Replace them with the newer guard(mutex)() for cleaner RAII patterns and to improve maintainability. Add new helper function scd30_trigger_handler_helper() containing the critical section for scd30_trigger_handler(). In addition, small refactor to replace "?:" operator with regular if/else returns.

iio: chemical: sps30: Replace manual locking with RAII locking

2026-05-31T10:01:48+00:00

Replace manual mutex_lock() and mutex_unlock() calls with the much newer guard(mutex)() macro to enable RAII patterns, modernize the driver, and to increase readability. Move mutex locking into sps30_do_meas() and tune it up to use guard()(), as every caller takes the lock anyways. Signed-off-by: Maxwell Doose Signed-off-by: Jonathan Cameron

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.

Use BME680_NUM_CHANNELS instead of the hardcoded channel count in the scan buffer. This avoids use of a magic number and improves code readability and maintainability. Suggested-by: Jonathan Cameron Signed-off-by: Nikhil Gautam Signed-off-by: Jonathan Cameron

iio: chemical: scd30: reject (response=NULL, size>0) in scd30_i2c_command()

2026-05-31T09:59:37+00:00

scd30_i2c_command() takes an opaque "response" buffer plus its size. At the start of the function the code already checks if response is NULL (via the rsp local), but the response-decoding loop after the i2c transfer always dereferences rsp without re-checking. With the current callers in scd30_core.c this is harmless, since write commands pass response=NULL together with size=0 (so the loop body is never entered). The (response=NULL, size>0) combination has no useful meaning: there is nowhere to put the bytes that come back from the chip. Treat it as an invalid argument and bail out at the top of the function with -EINVAL, instead of silently doing the i2c transfer and dereferencing a NULL pointer in the decode loop. smatch flagged the inconsistency: drivers/iio/chemical/scd30_i2c.c:104 scd30_i2c_command() error: we previously assumed rsp could be null (see line 77) No functional change for the existing callers, which only ever use (response=NULL, size=0) for writes and (response!=NULL, size>0) for reads.

iio: Move MODULE_DEVICE_TABLE next to the table itself

2026-05-31T09:59:34+00:00

By convention MODULE_DEVICE_TABLE() immediately follows the ID table it exports, because this is easier to read and verify. It also makes more sense since #ifdef for ACPI or OF could hide both of them. Most of the drivers already have this correctly placed, so adjust the missing ones. No functional impact.
