So you want to remove vgic_destroy() and vgic_create() from vgic.c and
vgic.h and use a static version of it in vgic-v[23]-emul.c instead?
To avoid the two prototypes and make the declaration of the struct
kvm_device_ops look nicer? Did I got this right?
I did that now, it looks a bit neater, at the cost of small code
duplication of admittedly trivial code. So as long as there isn't
something added to those functions, that's probably fine.
So I will include it in the next version.
Cheers,
Andre.
