Subject: hw/hyperv/balloon: Consolidate OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=8cab2354a2ff77c0977ac337a93ad6f645e5086a;p=thirdparty%2Fqemu.git

hw/hyperv/balloon: Consolidate OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES

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.
