70788d26ae iio: normalize array sentinel style
Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.

For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

6a9262edff iio: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/iio/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

374c6deea7 iio: hid-sensor: Use aligned data type for timestamp
Use aligned_s64 for the timestamp field.

Note, the actual data is signed, hence with this we also amend that.
While at it, drop redundant __alignment directive.

94f2dab24e iio: position: hid-sensor-custom-intel-hinge: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

fb226ae750 iio: hid-sensors: Update header includes
General driver churn doesn't always include updates of header includes.
Manual review of the output of the include-what-you-use checker lead to the
following cleanup. Hopefuly this brings things back to a good state for the
hid-sensor drivers.

12f13d1fae iio: hid-sensors: lighten exported symbols by moving to IIO_HID namespace
A namespace for exported symbols makes clear who is a provider
and who is a consumer of the certain resources. Besides that,
it doesn't pollute the common namespace.

0e41fd515f iio: hid-sensors: Move get sensitivity attribute to hid-sensor-common
No functional change has been made with this patch. The main intent here
is to reduce code repetition of getting sensitivity attribute.

In the current implementation, sensor_hub_input_get_attribute_info() is
called from multiple drivers to get attribute info for sensitivity
field. Moving this to common place will avoid code repetition.

660987e125 iio: hid-sensors: Add hinge sensor driver
The Hinge sensor is a common custom sensor on laptops. It calculates
the angle between the lid (screen) and the base (keyboard). In addition,
it also exposes screen and the keyboard angles with respect to the
ground. Applications can easily get laptop's status in space through
this sensor, in order to display appropriate user interface.
