Subject: isa: New isa_new(), isa_realize_and_unref() etc.
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0fe9d9011971820b2dab27aa49cfb957b91cc3e2;p=qemu.git

isa: New isa_new(), isa_realize_and_unref() etc.

I'm converting from qdev_create()/qdev_init_nofail() to
qdev_new()/qdev_realize_and_unref(); recent commit "qdev: New
qdev_new(), qdev_realize(), etc." explains why.

ISA devices use qdev_create() through isa_create() and
isa_try_create().

Provide isa_new(), isa_try_new(), and isa_realize_and_unref() for
converting ISA devices.
