[Qemu-devel] [PATCH 4/8] block: Drop BB name from bad option error

[Max Reitz <mreitz@redhat.com>]

The information which BB is concerned does not seem useful enough to
justify its existence in most other place (which may be related to qemu
printing the -drive parameter in question anyway, and for blockdev-add
the attribution is naturally unambiguous). Furthermore, as of a future
patch, bdrv_get_device_name(bs) will always return the empty string
before bdrv_open_inherit() returns.

Therefore, just dropping that information seems to be the best course of
action.
