Subject: [PATCH v2 01/11] KVM: arm64: Drop unused vcpu param to kvm_psci_valid_affinity()
Date: Thu, 23 Sep 2021 19:16:00 +0000 [thread overview]
Message-ID: <20210923191610.3814698-2-oupton@google.com> (raw)
In-Reply-To: <20210923191610.3814698-1-oupton@google.com>
The helper function does not need a pointer to the vCPU, as it only
consults a constant mask; drop the unused vcpu parameter.
