This goes a little further and converts all ST drivers using the st_common
bits to devm functions.
As mentioned by Jonathan, the devm unwind is often attached to
iio_dev->dev.parent, and something it's attached to some other pointer
which references the same device object.

In the last patch, that point is removed, to eliminate doubt about this
mix-n-match.
An alternative would be an assert/check somewhere to ensure that
'iio_dev->dev.parent == adata->dev'. But I [personally] don't like it that
much.

As mentioned previously, I was also thinking of sending this set with the
previous one. But I am usually reserved to send large sets; also, because I
don't really like to review large sets [when I'm reviewing other people's
code].

Alexandru Ardelean (4):
iio: st_sensors: remove st_sensors_deallocate_trigger() function
iio: st_sensors: remove st_sensors_power_disable() function
iio: st_sensors: remove all driver remove functions
iio: st_sensors: remove reference to parent device object on
st_sensor_data
