b5821e6038 iio: dac: stm32-dac-core: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

5ff1f75400 iio: adc: axp20x: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

e670bfe273 iio: addac: ad74413r: update channel function set
According to the datasheet switching to a new channel function implies
multiple steps.

All functions must be selected for a minimum of 130 μs before changing
to another function.
The DAC_CODEx registers are not reset by changing channel functions.
Prior to changing channel functions, it is recommended to set the DAC
code to 0x0000 via the DAC_CODEx registers. Set the channel function
to high impedance via the CH_FUNC_SETUPx registers before transitioning
to the new channel function. After the new channel function is configured,
it is recommended to wait 150 μs before updating the DAC code.

Even though the channel switch is done at only at probe, where a device
reset is performed, that does not guarantee that the steps prior
changing to new channel function should be neglected.
