This is the 7th and final set of changes to convert all drivers over to
use and finally enforce add_disk() error handling. 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.

  block: make __register_blkdev() return an error
  block: add __must_check for *add_disk*() callers
