Thanks - this points at the backport of c34b09cbd6fc0 ("s390/cio: Update
purge function to unregister the unused subchannels") which had its own
issues on 6.6.y. I reverted c34b09cbd6fc0 on 6.6 so 6.6.142
should build cleanly without the manual fix. If the upstream purge
update is still wanted on 6.6, it can be re-submitted as a proper
backport once the driver-core prerequisites are in 6.6.142.
