Merge tag 'iio-fixes-for-5.4a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
Jonathan writes: First set of IIO fixes for the 5.4 cycle. * adis16400 - Make sure to free memory on a few failure paths. * adxl372 - Fix wrong fifo depth - Fix wrong indexing of data from the fifo. - Perform a reset at startup to avoid a problem with inconsistent state. * axp288 - This is a fix for a fix. The original fix made sure we kept the configuration from some firmwares to preserve a bias current. Unfortunately it appears the previous behaviour was working around a buggy firmware by overwriting the wrong value it had. Hence a regression was seen. * bmc150 - Fix the centre temperature. This was due to an error in one of the datasheets. * hx711 - Fix an issue where a badly timed interrupt could lead to a control line being high long enough to put the device into a low power state. * meson_sar_adc - Fix a case where the irq was enabled before everything it uses was allocated. * st_lsm6dsx - Ensure we don't set the sensor sensitivity to 0 as it will force all readings to 0. - Fix a wait time for the slave i2c controller when the accelerometer is not enabled. * stm32-adc - Precursor for fix. Move a set of register definitions to a header. - Fix a race when several ADCs are in use with some using interrupts to control the dataflow and some using DMA. * vcnl4000 - Fix a garbage of_match_table in which a string was passed instead of the intended enum. * tag 'iio-fixes-for-5.4a' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: iio: Fix an undefied reference error in noa1305_probe iio: light: opt3001: fix mutex unlock race iio: adc: ad799x: fix probe error handling iio: light: add missing vcnl4040 of_compatible iio: light: fix vcnl4000 devicetree hooks iio: imu: st_lsm6dsx: fix waitime for st_lsm6dsx i2c controller iio: adc: axp288: Override TS pin bias current for some models iio: imu: adis16400: fix memory leak iio: imu: adis16400: release allocated memory on failure iio: adc: stm32-adc: fix a race when using several adcs with dma and irq iio: adc: stm32-adc: move registers definitions iio: accel: adxl372: Perform a reset at start up iio: accel: adxl372: Fix push to buffers lost samples iio: accel: adxl372: Fix/remove limitation for FIFO samples iio: adc: hx711: fix bug in sampling of data iio: fix center temperature of bmc150-accel-core iio: imu: st_lsm6dsx: forbid 0 sensor sensitivity iio: adc: meson_saradc: Fix memory allocation order
