With Linux 6.2.1, I get the same error "Serial bus multi instantiate pseudo device driver CSC3551:00: error -ENOENT: Error requesting irq at index 0". I guess your patch is not reached at all then.
If I understand correctly, this is somewhat unrelated to this original bug, maybe I should look further around CS35L41 and/or serial multi-instantiate driver?
