I agree about this in general, but for a different reason. There should be
only one call to object_realize_nofail, in vl.c, which might as well be
inlined---I'll include it in my series. All calls to qdev_init_nofail
and qdev_init should disappear from boards that are properly converted
to QOM. Next on my QOM list (for 1.2) is a scripted refactoring to
ISADevice *rtc_init(ISABus *bus, int base_year, qemu_irq intercept_irq);
to
ISADevice *rtc_new(ISABus *bus, int base_year, qemu_irq intercept_irq);
static ISADevice *rtc_init(ISABus *bus, int base_year, qemu_irq intercept_irq)
{
ISADevice *dev = rtc_new(bus, base_year, intercept_irq);
qdev_init_nofail(dev);
return dev;
}
