From: Liam Beguin <[email protected]>
The iio-rescale driver supports various combinations of scale types and
offsets. These can often result in large integer multiplications. Make
sure these calculations are done right by adding a set of kunit test
cases that build on top of iio-test-format.
To run these tests, add the following to .kunitconfig
$ cat .kunitconfig
CONFIG_IIO=y
CONFIG_IIO_RESCALE_KUNIT_TEST=y
CONFIG_KUNIT=y
Then run:
$ ./tools/testing/kunit/kunit.py run --kunitconfig .kunitconfig

I didn't grok that either. My best guess is that the arch in question
(nds32) has some other config thingy that makes kunit build in some
weird way (or maybe not at all). But that's just a very wild guess
indeed.
I'll try to get to reviewing this new version, but I'm swamped at $-job
at the moment...
Cheers,

I only took a quick look at this, but was quite puzzled too.
I'll try to find more time to investigate.
