KVM: arm64: vgic-its: Add pointer to corresponding kvm_device (bb717644) · Commits · 戴 / test

Going from the ITS structure to the corresponding KVM structure would be quite handy at times. The kvm_device pointer that is passed at create time is quite convenient for this, so let's keep a copy of it in the vgic_its structure. This will be put to a good use in subsequent patches.
