11 daysiio: common: st_sensors: Fix use of uninitialize device structsMaud Spierings
commit 9f92e93e257b33e73622640a9205f8642ec16ddd upstream. Throughout the various probe functions &indio_dev->dev is used before it is initialized. This caused a kernel panic in st_sensors_power_enable() when the call to devm_regulator_bulk_get_enable() fails and then calls dev_err_probe() with the uninitialized device. This seems to only cause a panic with dev_err_probe(), dev_err(), dev_warn() and dev_info() don't seem to cause a panic, but are fixed as well. The issue is reported and traced here: [1] Link: https://lore.kernel.org/all/AM7P189MB100986A83D2F28AF3FFAF976E39EA@AM7P189MB1009.EURP189.PROD.OUTLOOK.COM/ [1] Cc: stable@vger.kernel.org Signed-off-by: Maud Spierings <maudspierings@gocontroll.com> Reviewed-by: Andy Shevchenko <andy@kernel.org> Link: https://...

11 daysiio: accel: fxls8962af: Fix use after free in fxls8962af_fifo_flushSean Nyekjaer
commit 1fe16dc1a2f5057772e5391ec042ed7442966c9a upstream. fxls8962af_fifo_flush() uses indio_dev->active_scan_mask (with iio_for_each_active_channel()) without making sure the indio_dev stays in buffer mode. There is a race if indio_dev exits buffer mode in the middle of the interrupt that flushes the fifo. Fix this by calling synchronize_irq() to ensure that no interrupt is currently running when disabling buffer mode.

[ Upstream commit 1bb942287e05dc4c304a003ea85e6dd9a5e7db39 ] The IIO ABI requires 64-bit aligned timestamps.

2025-05-18iio: accel: adxl367: fix setting odr for activity time updateLothar Rubusch
[ Upstream commit 38f67d0264929762e54ae5948703a21f841fe706 ] Fix setting the odr value to update activity time based on frequency derrived by recent odr, and not by obsolete odr value. The [small] bug: When _adxl367_set_odr() is called with a new odr value, it first writes the new odr value to the hardware register ADXL367_REG_FILTER_CTL. Second, it calls _adxl367_set_act_time_ms(), which calls adxl367_time_ms_to_samples(). Here st->odr still holds the old odr value. This st->odr member is used to derrive a frequency value, which is applied to update ADXL367_REG_TIME_ACT. Hence, the idea is to update activity time, based on possibilities and power consumption by the current ODR rate. Finally, when the function calls return, again in _adxl367_set_odr() the new ODR is assigned to st->odr. The fix: When setting a new ODR value is set to ADXL367_REG_FILTER_CTL, also ADXL367_REG_TIME_ACT should probably be updated with a frequency based on the recent ODR value and not the old one. Changing the location of the assignment to st->odr fixes this.

2024-12-09iio: accel: kx022a: Fix raw read formatMatti Vaittinen
commit b7d2bc99b3bdc03fff9b416dd830632346d83530 upstream. The KX022A provides the accelerometer data in two subsequent registers. The registers are laid out so that the value obtained via bulk-read of these registers can be interpreted as signed 16-bit little endian value. The read value is converted to cpu_endianes and stored into 32bit integer. The le16_to_cpu() casts value to unsigned 16-bit value, and when this is assigned to 32-bit integer the resulting value will always be positive. This has not been a problem to users (at least not all users) of the sysfs interface, who know the data format based on the scan info and who have converted the read value back to 16-bit signed value. This isn't compliant with the ABI however. This, however, will be a problem for those who use the in-kernel interfaces, especially the iio_read_channel_processed_scale(). The iio_read_channel_processed_scale() performs multiplications to the returned (always positive) raw value, which will cause strange results when the data from the sensor has been negative. Fix the read_raw format by casting the result of the le_to_cpu() to signed 16-bit value before assigning it to the integer. This will make the negative readings to be correctly reported as negative. This fix will be visible to users by changing values returned via sysfs to appear in correct (negative) format.

2024-07-04Merge tag 'iio-for-6.11b' of ↵Greg Kroah-Hartman
ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next Jonathan writes: IIO: 2nd set of new device support, features and cleanup for 6.11 The big one here is we finally have Paul Cercueil's (and others) DMA buffer support for IIO devices enabling high speed zero copy transfer of data to and from sensors supported by IIO (and for example USB). This should aid with upstream support of a range of higher performance ADCs and DACs. Two merges from other trees - spi/spi_devm_optimize used for simplification in ad7944. - dmaengine/topic_dma_vec to enable the DMABUF series. One feature with impact outside IIO. - Richer set of dev_err_probe() like helpers to cover ERR_PTR() cases. New device support ================== adi,ad7173 - Add support for AD4111, AD4112, AD4114, AD4115 and ADC4116 pseudo differential ADCs. Major driver rework was needed to enabled these. adi,ad7944 - Use devm_spi_optimize_message() to avoid a local devm cleanup callback. This is the example case from the patch set, others will follow. mediatek,mt6359-auxadc - New driver for this ADC IP found in MT6357, MT6358 and MT6359 PMICs. st,accel - Add support for the LIS2DS12 accelerometer ti,ads1119 - New driver for this 16 bit 2-differential or 4-single ended channel ADC. Features ======== dt-bindings - Introduce new common-mode-channel property to help handle pseudo differential ADCs where we have something that looks like one side of differential input, but which is only suited for use with a slow moving reference. adi,adf4350 - Support use as a clock provider. iio-hmwon - Support reading of labels from IIO devices by their consumers and use this in the hwmon bridge. Cleanup and minor fixes ======================= Treewide - Use regmap_clear_bits() / regmap_set_bits() to simplify open coded equivalents. - Use devm_regulator_get_enable_read_voltage() to replace equivalent opencoded boilerplate. In some cases enabled complete conversion to devm handling and removal of explicit remove() callbacks. - Introduce dev_err_ptr_probe() and other variants and make use of of them in a couple of examples driver cleanups. Will find use in many more drivers soon. adi,ad7192 - Introduce local struct device *dev and use dev_err_probe() to give more readable code. adi,adi-axi-adc/dac - Improved consistency of messages using dev_err_probe() adi,adis - Split the trigger handling into cases that needed paging and those that don't resulting in more readable code. - Use cleanup.h to simplify error paths via scoped cleanup. - Add adis specific lock helpers and make use of them in a number of drivers. adi,ad7192 - Update maintainer (Alisa-Dariana Roman) adi,ad7606 - dt-binding cleanup. avago,apds9306 - Add a maintainer entry (Subhajit Ghosh) linear,ltc2309 - Fix a wrong endian type. st,stm32-dfsdm - Fix a missing port property in the dt-binding. st,sensors - Relax whoami match failure to a warning print rather than probe failure. This enables fallback compatibles to existing parts from those that don't necessarily even exit yet. * tag 'iio-for-6.11b' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (112 commits) iio: adc: ad7173: Fix uninitialized symbol is_current_chan iio: adc: Add support for MediaTek MT6357/8/9 Auxiliary ADC math.h: Add unsigned 8 bits fractional numbers type dt-bindings: iio: adc: Add MediaTek MT6359 PMIC AUXADC iio: common: scmi_iio: convert to dev_err_probe() iio: backend: make use of dev_err_cast_probe() iio: temperature: ltc2983: convert to dev_err_probe() dev_printk: add new dev_err_probe() helpers iio: xilinx-ams: Add labels iio: adc: ad7944: use devm_spi_optimize_message() Documentation: iio: Document high-speed DMABUF based API iio: buffer-dmaengine: Support new DMABUF based userspace API iio: buffer-dma: Enable support for DMABUFs iio: core: Add new DMABUF interface infrastructure MAINTAINERS: Update AD7192 driver maintainer iio: adc: ad7192: use devm_regulator_get_enable_read_voltage iio: st_sensors: relax WhoAmI check in st_sensors_verify_id() MAINTAINERS: Add AVAGO APDS9306 dt-bindings: iio: adc: adi,ad7606: comment and sort the compatible names dt-bindings: iio: adc: adi,ad7606: add missing datasheet link ...

2024-05-27iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0Uwe Kleine-König
These drivers don't use the driver_data member of struct i2c_device_id, so don't explicitly initialize this member. This prepares putting driver_data in an anonymous union which requires either no initialization or named designators. But it's also a nice cleanup on its own. While add it, also remove commas after the sentinel entries.

2024-04-29iio: accel: mxc4005: Read orientation matrix from ACPI ROTM methodHans de Goede
Some devices use the semi-standard ACPI "ROTM" method to store the accelerometers orientation matrix. Add support for this using the new iio_read_acpi_mount_matrix() helper, if the helper fails to read the matrix fall back to iio_read_mount_matrix() which will try to get it from device-properties (devicetree) and if that fails it will fill the matrix with the identity matrix.

If kxcjk-1013 ACPI devices with another HID have a ROTM method that should still be parsed and if the method is not there then iio_read_acpi_mount_matrix() will fail silently. Acked-by: Rafael J.
