2022-11-23iio: adc: cc10001: Use devm_clk_get_enabled() to avoid boilerplate.Jonathan Cameron1-15/+5
As this driver just enables clock in probe() and disables in remove() we can use this new function to replace boilerplate and simplify error paths.

2022-11-23iio: Don't silently expect attribute typesMatti Vaittinen15-51/+55
The iio_triggered_buffer_setup_ext() and the devm_iio_kfifo_buffer_setup_ext() were changed by commit 15097c7a1adc ("iio: buffer: wrap all buffer attributes into iio_dev_attr") to silently expect that all attributes given in buffer_attrs array are device-attributes. This expectation was not forced by the API - and some drivers did register attributes created by IIO_CONST_ATTR(). When using IIO_CONST_ATTRs the added attribute "wrapping" does not copy the pointer to stored string constant and when the sysfs file is read the kernel will access to invalid location. Change the function signatures to expect an array of iio_dev_attrs to avoid similar errors in the future. Merge conflict resolved whilst applying due to patch crossing with two new drivers (kx022a accelerometer and ad4130 ADC).

KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ, tap/motion detection, wake-up & back-to-sleep events, four acceleration ranges (2, 4, 8 and 16g), and probably some other cool features. Add support for the basic accelerometer features such as getting the acceleration data via IIO. (raw reads, triggered buffer [data-ready] or using the WMI IRQ). Important things to be added include the double-tap, motion detection and wake-up as well as the runtime power management.

2022-11-23iio: amplifier: hmc425a: simplify using devm_regulator_get_enable()Matti Vaittinen1-16/+1
Drop open-coded pattern: 'devm_regulator_get(), regulator_enable(), add_action_or_reset(regulator_disable)' and use the devm_regulator_get_enable() and drop the pointer to the regulator. This simplifies code and makes it less tempting to add manual control for the regulator which is also controlled by devm.

Use devm_regulator_bulk_get_enable() instead of open coded bulk-get, bulk-enable, add-action-to-disable-at-detach - pattern. A functional change (which seems like a bugfix) is that if regulator_bulk_get fails, the enable is not attempted.
