[Qemu-devel] [PATCH 10/10] machine: Set MachineClass::name automatically

[Eduardo Habkost <ehabkost@redhat.com>]

Now all TYPE_MACHINE subclasses use MACHINE_TYPE_NAME to generate the
class name. So instead of requiring each subclass to set
MachineClass::name manually, we can now set it automatically at the
TYPE_MACHINE class_base_init() function.
