The module loader will now trigger test execution. This frees up the module_init function for other uses. - Instead of storing an array of arrays of suites, have the kunit_test_suite() and kunit_test_suites() macros append to one global (or per-module) list of test suites. This removes a needless layer of indirection, and removes the need to NULL-terminate suite_sets. The upshot of this is that it should now be possible to use the kunit_test_suite() and kunit_test_suites() macros to register test suites even from within modules which otherwise had module_init functions. This was proving to be quite a common issue, resulting in several modules calling into KUnit's private suite execution functions to run their tests (often introducing incompatibilities with the KUnit tooling). This series also fixes the thunderbolt, nitro_enclaves, and sdhci-of-aspeed tests to use kunit_test_suite() now that it works. This is required, as otherwise the first two patches may break these tests entirely. Huge thanks to Jeremy Kerr, who designed and implemented the module loader changes, and to Daniel Latypov for pushing the simplification of the nested arrays in .kunit_test_suites. I've tested this series both with builtin tests on a number of architectures, and with modules on x86_64, and it seems good-to-go to me. More testing (particularly of modules) with more interesting setups never hurts, though!
