Subject: [PATCH 2/3] KVM: PPC: Book3S HV: Delay setting of kvm ops
Date: Thu, 23 Dec 2021 21:19:30 +0000	[thread overview]
Message-ID: <20211223211931.3560887-3-farosas@linux.ibm.com> (raw)
In-Reply-To: <20211223211931.3560887-1-farosas@linux.ibm.com>

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.
