[PATCH 2/3] KVM: PPC: Book3S HV: Delay setting of kvm ops

From: Fabiano Rosas <hidden>
Date: 2021-12-23 21:22:32
Subsystem: kernel virtual machine for powerpc (kvm/powerpc), linux for powerpc (32-bit and 64-bit), the rest · Maintainers: Madhavan Srinivasan, Linus Torvalds

Delay the setting of kvm_hv_ops until after all init code has
completed. This avoids leaving the ops still accessible if the init
fails.
