[PATCH v2 0/2] block: 7th -- last batch of add_disk() error handling conversions

[Luis Chamberlain <mcgrof@kernel.org>]

This is the 7th and last set of driver conversions for add_disk() error
handling. The entire set of pending changes can be found on my
20210927-for-axboe-add-disk-error-handling branch [0].

Changes on this v2:

  - rebased onto linux-next tag 20210927
  - I modified the drivers to be sure to treat an existing block device on
    probe as a non-issue, and expanded the documentation to explain why we
    want to driver's probe routine to behave this way.

  block: make __register_blkdev() return an error
