[PATCH 0/3] block: simple *add_disk*() driver conversions

[Luis Chamberlain]

As requested by Christoph, I'm going to add a few demo driver
conversions, to show how drivers can manage *add_disk*() error
handling.

I've converted all drivers at this point, but I think it makes sense to
split these conversion up into groups. This is the first group, which
demos trivial changes. This group is larger than this, but this series
with 3 driver examples should suffice to start review on that group type.

If this seems fine and the block changes get merged I can extend this
group later to include all trivial driver conversions. But patch review
on these would help to get started.

Luis Chamberlain (3):
  loop: add error handling support for add_disk()
  null_blk: add error handling support for add_disk()
  nbd: add error handling support for add_disk()
