iio_push_to_buffers_with_timestamp()
To make code more readable, use a structure to express the channel
layout and ensure the timestamp is 8 byte aligned.
Found during an audit of all calls of uses of
iio_push_to_buffers_with_timestamp()
Fixes: 0d96d5ead3f7 ("iio: humidity: Add triggered buffer support for AM2315")

With CONFIG_ACPI=n and -Werror, 0-day reports:
drivers/iio/humidity/am2315.c:259:36: error:
'am2315_acpi_id' defined but not used
According to Andy Shevchenko, the ACPI ID used in this driver is fake
and does not really exist. Remove it and with it ACPI support from
the driver.
Note that, if an explicit of_device_id table is added to the driver
it could support the PRP0001 based ACPI approach.

Remove kernel-doc keyword from function header comment.
It fixes issues spotted by scripts/kernel-doc like:
drivers/iio/<driver>.c:3: info: Scanning doc for function <component name>
drivers/iio/<driver>.c:X: warning: expecting prototype for <component name>.
Prototype was for <function>() instead
To reproduce the errors:
scripts/kernel-doc -v -none $(find drivers/iio/ -name \*.c \
-exec head -2 {} \+ | grep -B2 -e '\*\*' | grep '==' | cut -d ' ' -f 2)
After, confirm these errors are gone with:
scripts/kernel-doc -v -none $(git show --name-only | grep -e "^driver")

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.

Use device-managed APIs to simplify the code.
The remove functions are redundant now and can
be deleted.

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 I2C drivers have an i2c_device_id array but that information isn't
exported to the modules using the MODULE_DEVICE_TABLE() macro. So the
modules autoloading won't work if the I2C device is registered using
OF or legacy board files due missing alias information in the modules.
The issue was found using Kieran Bingham's coccinelle semantic patch:
