David Gow July 9, 2022, 3:19 a.m. UTC 
The new implementation of kunit_test_suite() for modules no longer
conflicts with module_init, so can now be used by the thunderbolt tests.

Also update the Kconfig entry to enable the test when KUNIT_ALL_TESTS is
enabled.

This means that kunit_tool can now successfully run and parse the test
results with, for example:
	./tools/testing/kunit/kunit.py run --arch=x86_64 \
	--kconfig_add CONFIG_PCI=y --kconfig_add CONFIG_USB4=y \
	'thunderbolt'

Changes since v3:
https://lore.kernel.org/linux-kselftest/20220625050838.1618469-4-davidgow@google.com/
- Rebase on top of the TAINT_TEST patch series. This should now apply
  cleanly on top of the kunit branch:
  https://lore.kernel.org/linux-kselftest/20220708044847.531566-1-davidgow@google.com/T/#u
- Add Brendan's Acked-by tag.

Changes since v2:
https://lore.kernel.org/linux-kselftest/20220621085345.603820-4-davidgow@google.com/
- Don't permit USB4_KUNIT_TESTS to be enabled when USB4=y and KUNIT=m
  i.e., add a dependency on (USB4=m || KUNIT=y)
  This would result in undefined kunit symbols being used, otherwise.
- Add Daniel's Acked-by

Changes since v1:
https://lore.kernel.org/linux-kselftest/20220618090310.1174932-4-davidgow@google.com/
- Actually include the Kconfig changes, which were mistakenly added to
  the next patch in the series in v1.
- Add Acked-by tag from Mika Westerberg
