There was already a bisection last Thursday which found this
commit, and Thierry explained that it works in linux-next thanks
to other patches.  I guess those patches are not going to be
cherry-picked onto the clk-next branch, so this will keep failing
until it's rebased.  Is that right?

If so, I can turn off bisections on clk-next for now.  We need to
have a way in KernelCI to tell that a commit has been fixed to
cope with this kind of situation in general.

Thanks,
Guillaume
