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.

When using the hrtimer iio trigger timestamp isn't updated.
If we use iio_get_time_ns it is updated correctly.

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.

This has been handled by the spi core for some time now.

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.

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.
