This change converts the probe hook to register the IIO device with
devm_iio_device_register() and register a hook with
devm_add_action_or_reset() to put the device in powerdown when the driver
gets unloaded.
Since the PM suspend/resume functions need only a reference to the
i2c_client object (which can be obtained from the base device object), the
i2c_set_clientdata() call can be removed.

These 2 functions only do I2C reads/writes and don't require any of the
private data of the driver.
They're also used in the PM suspend/resume part of the driver.
Converting them to take an i2c_client object as parameter simplifies things
a bit (especially in the suspend/resume) as the driver mostly needs the
reference for i2c_client, so no need to jump through hoops to get it from
the private data (as was done in many places).
The rfd77402_measure() function has also been converted to take an
i2c_client object, since it also does only I2C ops.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.
