QEMU currently abort()s if the user tries to specify the mmio_interface device without parameters: x86_64-softmmu/qemu-system-x86_64 -nographic -device mmio_interface qemu-system-x86_64: /home/thuth/devel/qemu/util/error.c:57: error_setv: Assertion `*errp == ((void *)0)' failed. Aborted (core dumped) This happens because the realize function is trying to set the errp twice in this case. After setting an error, the realize function should immediately return instead.
