I have ran this on the latest mainline. I can confirm that the errors are
nicely handled there. It triggers a warning and panics in device_add_disk()
because of:
return WARN_ON_ONCE(ret); /* keep until all callers handle errors */
and
Kernel panic - not syncing: panic_on_warn set ...

I will close the issue.
