[PULL 03/33] hw/vfio/ccw: Simplify using DEVICE() macro

Posted by Thomas Huth 2 years, 11 months ago

From: Philippe Mathieu-Daudé <philmd@linaro.org>

QOM parenthood relationship is:

  VFIOCCWDevice -> S390CCWDevice -> CcwDevice -> DeviceState

We can directly use the QOM DEVICE() macro to get the parent object.
