commit 5afc1540f13804a31bb704b763308e17688369c5 upstream.
Currently the for-loop that scans for the optimial adc_period iterates
through all the possible adc_period levels because the exit logic in
the loop is inverted. I believe the comparison should be swapped and
the continue replaced with a break to exit the loop at the correct
point.

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.

The equivalent of both of these are now done via macro magic when
the relevant register calls are made. The actual structure
elements will shortly go away.

The suspend/resume functions were using dev_to_iio_dev() to get
the iio_dev. That only works on IIO dev's. Use dev_get_drvdata()
for a platform device to get the correct iio_dev.

Palmas gpadc IRQs are nested threaded and this flag is not required for nested
irqs anymore, since commit 3c646f2c6aa9 ("genirq: Don't suspend nested_thread
irqs over system suspend") was merged.
