This patch fixes booting for me, so it should be applied as a fix and
tagged with:

Fixes: 5a46079a9645 ("PM: domains: Delete usage of driver_deferred_probe_check_state()")

If there are dependencies to the other patches in this series, it might
make sense to revert commit 5a46079a9645 instead.

Anyways, thanks for fixing the issue, for this patch:

For the process, looks like the earlier series got merged despite the
issues reported. And we had non-booting Linux next for at least some SoCs
for weeks. And now we are about to have a non-booting -rc1 unless things
get fixed fast. Annoying glitches, sigh..

Regards,

Tony
