iio: Add basic unit test for iio_format_value()
The IIO core provides a function to do formatting of fixedpoint numbers.
In the past there have been some issues with the implementation of the
function where for example negative numbers were not handled correctly.
Introduce a basic unit test based on kunit that tests the function and
ensures that the generated output matches the expected output.
This gives us some confidence that future modifications to the function
implementation will not break ABI compatibility.
To run the unit tests follow the kunit documentation and add
CONFIG_IIO=y
CONFIG_IIO_TEST_FORMAT=y
to the .kunitconfig and run
> ./tools/testing/kunit/kunit.py run
