Hi Hans,

Gerd is currently out so I just gave the patch you provided against
capability-search-v14 a try on s390. Didn't see any issues with the
previously broken device probing. As I understand it Bjorn asked you to
send a complete v15 and then for people to test that. I like that
approach and would prefer to provide a Tested-by for v15 rather than
via a patch on top. Gerd should be back next week too. Does that work
for you?

Thanks,
Niklas Schnelle
