Merge tag 'linux-kselftest-kunit-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest

Pull KUnit updates from Shuah Khan:
 "Several fixes, cleanups, and enhancements to tests and framework:

   - introduce _NULL and _NOT_NULL macros to pointer error checks

   - rework kunit_resource allocation policy to fix memory leaks when
     caller doesn't specify free() function to be used when allocating
     memory using kunit_add_resource() and kunit_alloc_resource() funcs.

   - add ability to specify suite-level init and exit functions"
