df9f7d4c33 iio: accel: bma220: Group IIO headers together
Group IIO headers together and follow the common pattern of header inclusion,
i.e. more generic first.

846afc1dbc iio: accel: bma220: Drop ACPI_PTR() and accompanying ifdeffery
The driver is quite likely used only on ACPI based platforms and
rarely build with CONFIG_ACPI=n. Even though, the few dozens of bytes
is better than ugly ifdeffery and inclusion of heavy header.

As a result, replace acpi.h with mod_devicetable.h.

Instead of using to_spi_dev() + spi_get_drvdata(),

938d1b3873 iio: accel: bma220: Convert to use ->read_avail()
Convert to use ->read_avail() instead of open-coded attribute handling.

While here, fix the typo in array definition and append comma in case of
the future extension.

5265b267e3 iio: accel: bma220: Fix returned codes from bma220_init(), bma220_deinit()
Potentially bma220_init() and bma220_deinit() may return positive codes.
Fix the logic to return proper error codes instead.

2d815b8415 iio: accel: bma220_spi: Do not define 'struct acpi_device_id' when !CONFIG_ACPI
Since ACPI_PTR() is used to NULLify the value when !CONFIG_ACPI,
struct 'bma220_acpi_id' becomes defined but unused.

Fixes the following W=1 kernel build warning(s):

 drivers/iio/accel/bma220_spi.c:312:36: warning: ‘bma220_acpi_id’ defined but not used [-Wunused-const-variable=]
 312 | static const struct acpi_device_id bma220_acpi_id[] = {
 | ^~~~~~~~~~~~~~

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.

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