Remove unneeded blank lines where they separate the data type definitions
and the macros which are using them.

b9493d5952 iio: accel: adxl345: Add ACPI HID table 
x86 boards may use ACPI HID "ADS0345" for adxl345 device.

Analog replied:
"ADS034X is not a valid PNP ID. ADS0345 would be.
I'm not aware that this ID is already taken.
Feel free to submit a mainline Linux input mailing list patch."

So add an ACPI match table for that accordingly.

Since ACPI device may not match to any I2C ID, use the name and type
directly from ACPI ID table in absence of I2C ID.

field in the OF device ID table.

While at it, make sure that device type is not 0 which may be wrongly
interpreted by device property APIs in the future.

0a18114d3f iio:accel:adxl345: Move exports into IIO_ADXL345 namespace

driver core exports into their own namespace and import that into the two

d372e5a19a iio: accel: adxl345: convert probe to device-managed functions 
This driver has two parts, one for i2c and one for spi, since the chip can
operate with both wire protocols.

The core file has a common adxl345_core_remove() function which puts the
chip into a powerdown state. This can be implemented with a
devm_add_action_or_reset() hook.

Doing that means we can register the IIO device with
devm_iio_device_register() and get rid of the adxl345_core_remove()
function.

The dev_set_drvdata() call can be removed as there is no other user of this
private data anymore.

6b8471e460 iio: adxl345: move null check for i2c id at start of probe 
Fixes ef89f4b96a ("iio: adxl345: Add support for the ADXL375").

This was found via static checker.
After looking into the code a bit, it's unlikely that there will be a NULL
dereference if the `id` object in that specific code path.
However, it's safe to add a NULL (paranoid) check just to make sure and
remove any uncertainties.

ef89f4b96a iio: adxl345: Add support for the ADXL375 
The ADXL375 is fully register map compatible to the ADXL345 (including the
device ID register returning the same value ...).

The only difference is the resolution of the acceleration sensor. The
ADXL375 can measure up to +-200g of acceleration.
