[PULL 06/24] hw/hyperv/balloon: Consolidate OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES

Posted by Philippe Mathieu-Daudé 5 months, 1 week ago

From: Zhao Liu <zhao1.liu@intel.com>

The QOM type of HvBalloon is declared by OBJECT_DECLARE_SIMPLE_TYPE,
which means it doesn't need the class!

Therefore, use OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES to implement
the type, then there's no need for class definition.
