None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>. Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

IIO_ST is going away as it is a pain to maintain so the simplest path with
this driver is to not specify the unused scan type.

Now that all drivers have been converted to the new event config interface we
can remove for the legacy event config interface. Also drop the '_new' suffix
for the event config interface callbacks, since those are the only callbacks
now.

The if check is redundant as the value obtained from
iio_device_register() is already in the required format.
Error messages are already printed by iio_device_register();
hence not needed.
