[PATCH 0/8] iio: Fix missing parent device initalization

[PATCH 0/8] iio: Fix missing parent device initalization

[Lars-Peter Clausen]

Add parent device initialization to drivers that are currently missing it.
Setting the parent device makes sure that the IIO device shows up at the
right level in the device hierachy.

The following coccinelle semantic patch was used to find the offending
drivers:
// <smpl>
@r1@
identifier indio_dev;
position p;
@@
indio_dev->dev.parent = ...;
...
(

Hmm. Took me a few moments to decide whether to push these as fixes or
not.  In the end I concluded that they have always been broken, so whilst
they are clearly a fix we want in, the probably don't need to be rushed
in or applied to old kernels. For drivers that were in this cycle, I
may push them out as straight forward fixes however.

If anyone disagrees then shout quickly!

Applied to the togreg branch of iio.git and pushed out as testing.

This makes sure that the IIO device appears the right level in the device
hierarchy.

Applied to the togreg branch of iio.git and pushed out as testing for the
