Alexandru Ardelean d3be83244c iio: remove explicit IIO device parent assignment
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.

Jonathan Cameron 6d9d020da5 iio:dpot: drop assign iio_info.driver_module
The equivalent of this is now done via macro magic when
the relevant register call is made.  The actual structure
elements will shortly go away.
