iio:common:ssp_sensors: Fix an error handling path ssp_probe()

2025-12-06T21:24:58+00:00

commit 21553258b94861a73d7f2cf15469d69240e1170d upstream. If an error occurs after a successful mfd_add_devices() call, it should be undone by a corresponding mfd_remove_devices() call, as already done in the remove function.

iio: common: st_sensors: Fix use of uninitialize device structs

2025-07-24T06:56:28+00:00

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 Reviewed-by: Andy Shevchenko Link: https://...

iio: invensense: fix multiple odr switch when FIFO is off

2024-12-09T09:41:09+00:00

commit ef5f5e7b6f73f79538892a8be3a3bee2342acc9f upstream. When multiple ODR switch happens during FIFO off, the change could not be taken into account if you get back to previous FIFO on value. For example, if you run sensor buffer at 50Hz, stop, change to 200Hz, then back to 50Hz and restart buffer, data will be timestamped at 200Hz. This due to testing against mult and not new_mult. To prevent this, let's just run apply_odr automatically when FIFO is off. It will also simplify driver code. Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

iio: st_sensors: relax WhoAmI check in st_sensors_verify_id()

2024-06-29T18:44:43+00:00

Hard matching against the WhoAmI values isn't ideal for using devices which are compatible with existing ones. Instead of raising an error, issue a warning instead, thus allowing the driver to continue probing.
