Subject: hw/isa/pc87312: Mark the device with user_creatable = false
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=35deebb2327227d8c5f4816476befb06f6329de6;p=qemu.git

hw/isa/pc87312: Mark the device with user_creatable = false

QEMU currently aborts if you try to use the device at the command
line:

$ ppc64-softmmu/qemu-system-ppc64 -S -machine prep -device pc87312
Unexpected error in qemu_chr_fe_init() at chardev/char-fe.c:222:
qemu-system-ppc64: -device pc87312: Device 'parallel0' is in use
Aborted (core dumped)

It uses parallel_hds in its realize function, so I can not be
instantiated by the user again.
