Merge tag 'linux_kselftest-kunit-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kerne...

Pull KUnit updates from Shuah Khan:

 - a new feature that adds APIs for managing devices introducing a set
   of helper functions which allow devices (internally a struct
   kunit_device) to be created and managed by KUnit.

   These devices will be automatically unregistered on test exit. These
   helpers can either use a user-provided struct device_driver, or have
   one automatically created and managed by KUnit. In both cases, the
   device lives on a new kunit_bus.

 - changes to switch drm/tests to use kunit devices

 - several fixes and enhancements to attribute feature

 - changes to reorganize deferred action function introducing
   KUNIT_DEFINE_ACTION_WRAPPER

 - new feature adds ability to run tests after boot using debugfs

 - fixes and enhancements to string-stream-test:
     - parse ERR_PTR in string_stream_destroy()
     - unchecked dereference in bug fix in debugfs_print_results()
     - handling errors from alloc_string_stream()
     - NULL-dereference bug fix in kunit_init_suite()
