I suspect the right thing is to just kill of ->probe.
The only thing it supports is pre-devtmpfs, pre-udev semantics that want to magically create disks when their pre-created device node is accesses. But if we don't remove it, yes I think not reporting the error is best. Just clean up whatever local resources were set up in the ->probe method and let the open fail without the need of passing on the actual error.
