Sorry to disappoint - linux-phy doesn't use b4 to build-test patches. It
gets them from Patchwork directly (as you'd get by clicking the 'diff' button),
then figures out whether to apply to the next or to the fixes branch
using the git-format-patch --subject-prefix string ('phy-next' or 'phy-fixes'),
then posts the checks back to Patchwork.

I can somehow imagine why no one rushed to improve this. While sometimes
somewhat useful, I can see the risk of such feature getting abused to
create a giant cobweb of dependencies that is suddenly no longer the
developer's problem, but passed on to somebody else.

In the future, please submit as RFC the patch sets that you know don't
directly apply, and mention that you're only posting them for early
feedback.
