X-Received-From: 2001:8b0:1d0::2 Subject: [Qemu-devel] [PULL 03/21] pc: simplify MachineClass::get_hotplug_handler handling X-BeenThere: qemu-devel@nongnu.org X-Mailman-Version: 2.1.21 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: qemu-devel-bounces+patchwork-qemu-devel=patchwork.kernel.org@nongnu.org Sender: "Qemu-devel" X-Virus-Scanned: ClamAV using ClamSMTP From: Igor Mammedov By default MachineClass::get_hotplug_handler is NULL and concrete board should set it to it's own handler. Considering there isn't any default handler, drop saving empty MachineClass::get_hotplug_handler in child class and make PC code consistent with spapr/s390x boards. We can bring this back when actual usecase surfaces and do it consistently across boards that use get_hotplug_handler().
