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.

This patch add support for Analog Devices (Linear Technology)
LTC2634 Quad 12-/10-/8-Bit Rail-to-Rail DAC.
The SPI functionality based on them from LTC2632 therefor
add the definitions only and update the Kconfig.

The documentation for ltc_2632_chip_info missed the desciption for the
num_channels. This trivial patch adds it.

The only difference between LTC2632 and LTC2636 is that the former has
two DAC channels while the latter has eight.

The channel data for ltc2632l12 and ltc2632h12 are identical. So there
is no gain in using two different (but identical) channel descriptions.
The only side effect of this change is some memory savings.

Almost all files in the kernel are either plain text or UTF-8 encoded. A
couple however are ISO_8859-1, usually just a few characters in a C
comments, for historic reasons.
This converts them all to UTF-8 for consistency.

Pointers chip_info and spi_dev_id are being assigned but are never used
hence they are redundant and can be removed.

The equivalent of this is now done via macro magic when
the relevant register call is made. The actual structure
element will shortly go away.
