git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus: Jonathan writes: First set of IIO fixes for the 5.2 cycle. * ads124 - Avoid a buffer overrun when setting an array to 0. * ads8688 - Don't use the pollfunc timestamp as it isn't set and would be wrong anyway for a device that does sampling on demand. * ds4422 - Fix masking on register used for chip verification. Wrong address was being read. * mpu6050 - Fix the fifo layout for ICM20602 to avoid underreading and hence failure to move on to the next record in the fifo. * NPCM ADC - Make sure there is actually a valid regulator before reading its voltage. * tag 'iio-fixes-for-5.2a' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: iio: adc: ti-ads8688: fix timestamp is not updated in buffer iio: dac: ds4422/ds4424 fix chip verification iio: imu: mpu6050: Fix FIFO layout for ICM20602 iio: adc: ads124: avoid buffer overflow iio: adc: modify NPCM ADC read reference voltage
2019-05-11iio: adc: ti-ads8688: fix timestamp is not updated in bufferSean Nyekjaer1-1/+1
When using the hrtimer iio trigger timestamp isn't updated. If we use iio_get_time_ns it is updated correctly.

2019-01-12iio: ti-ads8688: Update buffer allocation for timestampsDan Murphy1-1/+2
Per Jonathan Cameron, the buffer needs to allocate room for a 64 bit timestamp as well as the channels. Change the buffer to allocate this additional space.

The equivalent of both of these are now done via macro magic when the relevant register calls are made. The actual structure elements will shortly go away. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> Reviewed-by: Lars-Peter Clausen <lars@metafoo.de>
2016-09-05iio: devm_regulator_get_optional never returns NULLCrt Mori1-2/+2
This patch is inspired by a comment of Jonathan Cameron on patch of Linus Walleij commit aeb55fff3891834e07a3144159a7298a19696af8 ("iio: st_sensors: fetch and enable regulators unconditionally"). Because changes made in this patch are actually reference generators they should be using devm_regulator_get_optional, but if they do not explicitly set the reference to NULL they should not be using IS_ERR_OR_NULL, but simple IS_ERR check.
