If I have to guess (first time looking at this code), ACCEL_OPS_CLASS() is creating the class type QOM functions that the the second module_object_class_by_name() relies on to catch the module load error the commit is trying to address. I'm CCing Claudio to get a better idea of the intention here. At the very least we should add a code comment explaining the reasoning behind initing 'ops' two times in a row and so on.

I already detected it during the PULL request, but my message was missed at the time I think: https://lists.gnu.org/archive/html/qemu-devel/2022-11/msg01056.html So Reviewed-by: Claudio Fontana <cfontana@suse.de> Thanks, CLaudio
