[Qemu-devel] [PATCH 05/12] raven: Mark use of hw_error() in realize() FIXME

[Markus Armbruster <armbru@redhat.com>]

Device realize() methods aren't supposed to call hw_error(), they
should set an error and fail cleanly.  Blindly doing that would be
easy enough, but then realize() would fail without undoing its side
effects.  Just mark it FIXME for now.
