Helen's patch was needed, but there were still a couple of
issues. First we need to enable this extra option now in the
config fragment:
CONFIG_MEDIA_TEST_SUPPORT=y
as test_drivers/Kconfig starts with "if MEDIA_TEST_SUPPORT".
Then this Kconfig was included when MEDIA_PLATFORM_SUPPORT was
enabled rather than MEDIA_TEST_SUPPORT in media/Kconfig. So I've
just sent a patch to fix this dependency, and now it appears to
be generating the correct config. I did a full v4l2-compliance
run with the vivid driver on my local setup and it all passed.
