thunderbolt: Add KUnit tests for path walking (54509f50) · Commits · 戴 / test

This adds KUnit tests for path walking which is only dependent on software structures, so no hardware is needed to run these. We make these available only when both KUnit and the driver itself are built into the kernel image. The reason for this is that KUnit adds its own module_init() call in kunit_test_suite() which generates linker error because the driver does the same in nhi.c. This should be fine for now because these tests are only meant to run by developers anyway. Signed-off-by:
