iio: accel: HID: hid-sensor-accel-3d: Refactor channel initialization

2026-05-31T10:01:47+00:00

Clean up the channel initialization loop and replace the local accel_3d_adjust_channel_bit_mask() function with a compound literal to improve code readability.

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: accel: bmc150: Explicitly set .driver_data

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

There is one id entry that has an explicit assignment to .driver_data. To make the intention clearer, assign BOSCH_UNKNOWN (which is also 0) for all previously ids that had .driver_data = 0 implicitly before. While touching all entries in this array, convert to named initializers. Signed-off-by: Uwe Kleine-König (The Capable Hub) Signed-off-by: Jonathan Cameron

iio: common: ssp: remove SSP_CHAN_TIMESTAMP() macro

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

Remove the SSP_CHAN_TIMESTAMP() macro and replace users with the IIO_CHAN_SOFT_TIMESTAMP() macro. The SSP_CHAN_TIMESTAMP() macro is identical to the IIO_CHAN_SOFT_TIMESTAMP() macro, so we don't need a separate macro for it.

iio: accel: mma8452: Use dev_err_probe()

iio: accel: mma8452: switch to non-devm request_threaded_irq()

2026-05-31T09:59:42+00:00

Avoid using devm_request_threaded_irq() as the driver requires explicit error-handling path(s). Using devm_* API together with goto-based unwinding breaks the expected LIFO resource release model. Add explicit IRQ cleanup in the driver teardown paths to follow kernel resource management conventions. Signed-off-by: Sanjay Chitroda Signed-off-by: Jonathan Cameron

iio: accel: mma8452: handle I2C read error(s) in mma8452_read()

2026-05-31T09:59:42+00:00

Currently, If i2c_smbus_read_i2c_block_data() fails but mma8452_set_runtime_pm_state() succeeds, mma8452_read() returns 0. As a result, the caller mma8452_read_raw() assumes the read was successful and proceeds to use a buffer containing uninitialized stack memory. Add proper checking of the I2C read return value and propagate errors to the caller.

The "at least 5ms" wait after software reset has no specific upper bound. Use fsleep() with 5 * USEC_PER_MSEC to make the unit explicit at the call site. No functional change. Signed-off-by: Stepan Ionichev Reviewed-by: Andy Shevchenko Signed-off-by: Jonathan Cameron
