[Qemu-devel] [PATCH qom v3 07/14] qdev: gpio: Re-impement qdev_connect_gpio QOM style

[Peter Crosthwaite <peter.crosthwaite@xilinx.com>]

Re-implement as a link setter. This should allow the QOM framework to
keep track of ref counts properly etc.

We need to add a default parent for the connecting input incase it's
coming from a non-qdev source. We simply parent the IRQ to the machine
in this case.
