Thanks for confirmation, seems like this problem is indeed cured by your series.
Oki.
I still believe though that we shouldn't let 5.17 released with this warning being emitted into dmesg, so I'd suggest going with my patch for mainline, and revert it in your series on top of it.
No. That warning is only visible with CONFIG_PROVE_RAW_LOCK_NESTING with the following paragraph in its help: | NOTE: There are known nesting problems.

This warning in this call chain should affect every console driver which acquires a lock.
Thanks,
