[PATCH v2 0/9] drm: selftest: Convert to KUnit

[Maíra Canal]

Hi everyone,

Here is the v2 of the conversion of DRM selftests to KUnit. Some style changes
were made to align to the drm_format_helper series [1] and the documentation [2],
as renaming the kunit_suite and the test cases to use underscores as suggested,
changing the filenames and using a generic symbol to group all tests at the
config menu.

Moreover, in the previous version of the series, the drm_cmdline_parser tests
were broken into multiple test functions. As pointed out by Shuan Khan, it made
the tests harder to comprehend. So, the refactoring was dropped and
straightforward conversion of the tests was made without any functional changes.

Thanks for your attention and any feedback is welcomed!

Best Regards,
- Maíra Canal

v1 -> v2: https://lore.kernel.org/dri-devel/20220615135824.15522-1-maira.canal@xxxxxx/T/

- The suites no longer end in _tests (David Gow).
- Remove the TODO entry involving the conversion of selftests to KUnit (Javier Martinez Canillas).
- Change the filenames to match the documentation: use *_test.c (Javier Martinez Canillas).
- Add MODULE_LICENSE to all tests (kernel test robot).
- Make use of a generic symbol to group all tests - DRM_KUNIT_TEST (Javier Martinez Canillas).
- Add .kunitconfig on the first patch (it was on the second patch of the series).
- Straightforward conversion of the drm_cmdline_parser tests without functional changes (Shuah Khan)
- Add David's Tested-by tags
