iio: ssp_sensors: add more range checking in ssp_parse_dataframe()

2021-09-18T18:10:55+00:00

The "idx" is validated at the start of the loop but it gets incremented during the iteration so it needs to be checked again.

iio: ssp_sensors: fix error code in ssp_print_mcu_debug()

2021-09-18T18:09:49+00:00

The ssp_print_mcu_debug() function should return negative error codes on error. Returning "length" is meaningless. This change does not affect runtime because the callers only care about zero/non-zero.

iio/drivers/hid-sensor: use HZ macros

HZ unit conversion macros are available in units.h, use them and remove the duplicate definition.

iio: st-sensors: Remove some unused includes and add some that should be there

2021-07-24T14:59:00+00:00

The st-sensors drivers have changed in structure over time, and includes have not always kept up with this. Let's bring them back to nearer the ideal. Identified with the include-what-you-use tool and careful checking of its suggestions. Note I haven't been particularly aggressive here, so this is just the cases where the include obviously isn't needed rather than the more subtle corners. Note I took the opportunity to add mod_devicetable.h as I generally prefer to see that when acpi or of match tables are present.

iio: hid-sensors: Update header includes

2021-06-16T13:53:13+00:00

General driver churn doesn't always include updates of header includes. Manual review of the output of the include-what-you-use checker lead to the following cleanup. Hopefuly this brings things back to a good state for the hid-sensor drivers.

iio: hid-sensors: lighten exported symbols by moving to IIO_HID namespace

2021-06-16T13:53:13+00:00

A namespace for exported symbols makes clear who is a provider and who is a consumer of the certain resources. Besides that, it doesn't pollute the common namespace.

iio: hid: trigger: Balance runtime pm + use pm_runtime_resume_and_get()

2021-06-03T17:24:12+00:00

The call to pm_runtime_put_noidle() in remove() callback is not balanced by any gets Note this doesn't cause any problems beyond reader confusion as the runtime pm core protects against the reference counter going negative. Whilst here, use pm_runtiem_resume_and_get() to simplify code a little.

iio: core: move @id from struct iio_dev to struct iio_dev_opaque

2021-05-17T12:49:13+00:00

Continuing from Alexandru Ardelean's introduction of the split between driver modifiable fields and those that should only be set by the core. This could have been done in two steps to make the actual move after introducing iio_device_id() but there seemed limited point to that given how mechanical the majority of the patch is. Includes fixup from Alex for missing mxs-lradc-adc conversion. Signed-off-by: Jonathan Cameron Reviewed-by: Alexandru Ardelean Link: https://lore.kernel.org/r/20210426174911.397061-2-jic23@kernel.org
