If a driver does not assign an of_node to a IIO device to IIO core will
automatically assign the of_node of the parent device. This automatic
assignment is done in the iio_device_register() function.

There is a fair amount of drivers that currently manually assign the
of_node of the IIO device. All but 4 of them can make use of the automatic
assignment though.

The exceptions are:
 * mxs-lradc-adc: Which uses the of_node of the parent of the parent.
 * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node
   assigned to the IIO device before iio_device_register() is called.

All other drivers are updated to use automatic assignment. This reduces
the amount of boilerplate code involved in setting up the IIO device.

The patch has mostly been auto-generated with the following semantic patch

// <smpl>

expression indio_dev;

indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...)

FWIW,

I consider it an extremely right step to do. Actually we need to
switch to fwnode / device property API at the end.

Agreed on both fronts.  Will take a little while though to get
through all the drivers.  I'm also a tiny bit nervous that there
might be some gotchas hidden in the device property API changes
as I'm not familiar enough with them yet to do an 'automatic'
review...  That always makes me nervous when we can't track down
someone to test on a real system.

We'll get there in the end though.

Applied this to the togreg branch of iio.git and pushed out as
testing for the autobuilders to play with it.

Thanks,

Jonathan
