This set deals with those old drivers using __register_blkdev() which in turn have a respective add_disk() call made. The last patch ensures we won't add new drivers without a check for the add_disk() call. You can find the full set of patches on my kernel.org linux 20210901-for-axboe-add-disk-error-handling branch [0] which is now based on axboe/master.
